Compatibilization of polyethylene/poly(propylene)/polystyrene blends

Use of SEBS/EPR and SBR/EPR as Binary Compatibilizers for PE/PP/PS/HIPS Blends: A Work Oriented to the Recycling of Thermoplastic Wastes

“…Thus, one can conclude that yield stress and Young's modulus can not help in the determination of the main factors during blend processing. A similar result was reported by Fortenly et al9, 27, and they showed that the response of the tensile analysis usually is not used to discuss the behavior of polymer blends. However, the impact resistance (IR) showed significant differences between each experiment.…”

“…A temperature of 190 °C can be considered adequate since all polymers under study can be processed at this temperature. Many researchers have studied and reported that this temperature is adequate for processing this kind of materials9, 15, 23–29 and therefore one could assume that this temperature is also optimal for our work due to the fact that higher temperatures can degrade these materials.…”

“…Yield stress (s y ), Young's modulus (E), strain at break (e r ) and impact resistance (IR) of different samples as a function of temperature (T), time (t) and compatibilizer concentration (C). et al [9,27] , and they showed that the response of the tensile analysis usually is not used to discuss the behavior of polymer blends. However, the impact resistance (IR) showed significant differences between each experiment.…”

“…Actually, PET is easily recycled on a large scale but not PVC due to it being present in a small amount, thus a good way to consider the plastic waste is preparing materials constituted by different type of polymers such as PE, PP and PS. Fortelny et al9, 26–29 have worked on this subject and demonstrated that the mechanical properties of the materials obtained from the plastic waste were mainly affected by the degree of compatibility between them. They used poly(styrene‐ b ‐butadiene‐ b ‐styrene) (SBS), EPM, EPDM and ethylene‐propylene‐rubber (EPR) as compatibilizers to improve these properties.…”

Binary and ternary blends of polyethylene, polypropylene, and polyamide 6,6: The effect of compatibilization on the morphology and rheology

“…Most studies on polymer blends deal with binary systems, and the objective is to obtain desirable properties,1–5 For this purpose, compatibilizing agents are often used. Such agents are added to enhance the compatibility of two immiscible blend components by reducing the interfacial tension to obtain finer dispersions and enhanced phase adhesion and, at the same time, to improve the processing stability of blends by reducing coalescence effects 6–8. In the pursuit of new polymeric blend materials, attention has also been drawn to systems with more than two phases.…”
