“…Other authors have obtained similar results. For example, the same results were obtained by Tasdemir ( 2004) and Tasdemir and Karatop (2006) , who also saw a reduction in viscosity. He used styrene-butadiene-styrene (SBS) and styrene-isopren-styrene (SIS) as compatibilizers in blends of ABS / PC.…”

“…The objective of this second section is to recover this lost ductility through the addition of SEBS to the degraded ABS and to check how the viscosity, pressure in the cavity and shrinkage of the part is affected by the addition of SEBS to the degraded ABS. Other authors have recovered ductile properties through the incorporation of SIS, Tasdemir (2004), or SBS, Tasdemir and Karatop (2006), but these additives possess a C=C double bond structure which with time causes the crosslinking phenomenon to appear.…”

“…This variation in properties has been rectified by various authors through the use of additives or even by adding other polymers. For example, Tasdemir (2004) used styrene-butadiene-styrene (SBS) and Tasdemir and Karatop (2006) styrene-isopren-styrene (SIS) also as compatibilizers in mixtures of ABS/PC. SBS and SIS are materials that are very common in SEBS, but there appear to be no studies into incorporation of SEBS in recycled polymers in order to recover their properties.…”

“…Nearly all studies in this area highlight the crosslinking phenomena as the cause of the variation in properties that takes place (loss of ductility). In previous studies, such as those of Tasdemir (2004) and Tasdemir and Karatop (2006), SBS, SIS and styrene-butadiene rubber (SBR) have been used with the aim of recovering the ductility that is lost in some polymers, but the use of these polymers may cause crosslinking in future reprocessing cycles as in all cases there is a double C=C.…”

Recovery of recycled acrylonitrile-butadiene-styrene (ABS) through mixing with styrene-ethylene/butylene-styrene (SEBS) has been studied in this paper. To simulate recycled ABS, virgin ABS was processed through 5 cycles, at extreme processing temperatures, 220 ºC and 260 ºC. The virgin ABS, the virgin SEBS, the recycled ABS and the mixtures were mechanically, thermally and rheologically characterized after the various cycles of reprocessing in order to evaluate their corresponding properties and correlate them with the number of cycles undergone. With these data and using CAE (Computer Aided Engineering) the injection process was simulated by obtaining the optimal injection process parameters. Mixtures were injected at two temperatures in a sensorised mold correlating the shrinkage of the parts with temperature.The results show that tensile strength of ABS remains practically constant as the number of reprocessing cycles increases, while in the material injected with SEBS the tensile strength decreases. Concerning the Charpy notched impact strength; the values of the ABS reprocessed at 220 ºC remain more or less unchanged, while the values for 260 ºC show a significant decrease. The adhesion of the SEBS causes, in both cases, an increase in impact strength. DSC techniques enabled us to observe how the glass transition temperature (T g ) remains more or less constant regardless of the number of cycles or the temperature, whereas the crosslinking is much greater in the samples reprocessed at 260 ºC.Finally, the viscosity decreases with each cycle and this decrease becomes even more noticeable with the addition of SEBS, and also that the parts molded at lower temperatures have less shrinkage.

“…Una desventaja que poseen los termoplásticos es su variación de propiedades, no sólo por el efecto de los sucesivos procesos térmicos, sino también por efecto de su exposición a fenómenos atmosféricos, [1,2]. Esta variación de propiedades es subsanada por diversos autores mediante el uso de aditivos e incluso de otros polímeros, [3][4][5][6].…”

ABSTRACT:Recovery of recycled acrylonitrile-butadiene-styrene (ABS) through mixing with styrene-ethylene/butylene-styrene (SEBS) has been studied in this paper. To simulate recycled ABS, virgin ABS was processed through 5 cycles, at extreme processing temperatures, 220ºC and 260ºC. The virgin ABS, the virgin SEBS, the recycled ABS and the mixtures were mechanically and thermally characterized after the various cycles of reprocessing in order to evaluate their corresponding properties and correlate them with the number of cycles undergone.The results show that tensile strength of ABS remains practically constant as the number of reprocessing cycles increases, while in the material injected with SEBS the tensile strength decreases. Concerning the Charpy notched impact strength, the values of the ABS reprocessed at 220ºC remain more or less unchanged, while the values for 260ºC show a significant decrease. The adhesion of the SEBS causes, in both cases, an increase in impact strength. DSC techniques enabled us to observe how the glass transition temperature (Tg) remains more or less constant regardless of the number of cycles or the temperature, whereas the crosslinking is much greater in the samples reprocessed at 260ºC.As conclusion, it is suggested that the people who works handling and dealing with plastic that, when possible, use low temperatures of transformation of ABS instead of high temperatures. It is also recommended to recycle the ABS to those who work with it; to use 5% of SEBS added to the recycled ABS to recover the possible loss of properties.Keywords: Degradation, Recovery, ABS, SEBS, Injection, Processed, Mechanical characterization, Thermal characterization RESUMEN:En este trabajo se estudia la recuperación de un Acrilonitrilo-ButadienoEstireno (ABS) reciclado mediante mezcla con Estireno-Etileno/ Butadieno-Estireno (SEBS). Para simular el ABS reciclado se ha reprocesado ABS virgen durante cinco ciclos a las dos temperaturas extremas de procesamiento, 220ºC y 260ºC. Los materiales ABS virgen, SEBS virgen, ABS reprocesado y las mezclas han sido caracterizados mecánica y térmicamente para evaluar sus propiedades correspondientes y correlacionarlo con el número de ciclos de proceso.Los resultados muestran que la resistencia a tracción del ABS se mantiene prácticamente constante conforme aumenta el número de ciclos de reprocesado, en cambio, disminuye al aditivarlo con SEBS. Con respecto a la resistencia al impacto, los valores del ABS reprocesado a 220ºC permanecen prácticamente inalterables, mientras que para el reprocesado a 260ºC disminuyen de forma notable. La adhesión de SEBS provoca, en ambos casos, un incremento de energía de impacto. Las técnicas de DSC han permitido observar como la temperatura de transición vítrea se mantiene prácticamente constante independientemente del número de ciclos o de la temperatura; en cambio, el efecto de entrecruzamiento de las moléculas (crosslinking) es mucho mayor para las muestra reprocesadas a 260ºC.Como conclusión, se recomienda a los transformadores de p...

Interfacial agents as compatibilizers have recently been introduced into polymer blends to improve microstructure and mechanical properties of thermoplastics. In this way, it is possible to prepare a mixture of polymeric materials that can have superior mechanical properties over a wide temperature range. In this study, an incompatible blend of Polycarbonate (PC) and Acrylonitrile Butadiene Styrene (ABS) Copolymer were made compatible by addition of 5, 10, and 20% Styrene-Isopren-Styrene Copolymer (SIS). The mixing operation was conducted using a twinscrew extruder. The morphology and the compatibility of the mixtures were examined by SEM and DSC techniques.Furthermore, the elastic modulus, tensile and yield strengths, percentage elongation, hardness, melt flow index, Izod impact resistance, heat deflection temperature (HDT), Vicat softening point values of polymer alloys of various ratios were determined. It was found that addition of SIS to the structures decreased the tensile strength, yield strength, elastic modulus, and hardness, whereas it increased Izod impact strength and percentage elongation values.
