“…Furthermore, because the HBA/PET copolyester is a semi-rigid, rod-like aromatic polyester, it is less thermally stable than the wholly aromatic polyester. 21 The residual weight remaining after thermal decomposition has no relationship to thermal stability. The kinetic analysis of thermal decomposition makes it possible to predict the thermal stability and thermal decomposition behavior of polymers.…”

The thermal decomposition behavior and degradation characteristics of four different thermotropic liquid crystalline polymers (TLCPs) were studied. The thermal decomposition behavior was determined by means of thermogravimetric analysis (TGA) at different heating rates in nitrogen and air. The order of the thermal stability was as follows: multi-aromatic polyester > hydroxybenzoic acid (HBA)/hydroxynaphthoic acid (HNA) copolyester > HNA/ hydroxyl acetaniline (HAA)/terephthalic acid (TA) copolyester > HBA/Poly(ethylene terephthalate) (PET) copolyester. The activation energies of the thermal degradation were calculated by four multiple heating rate methods: Flynn-Wall, Friedman, Kissinger, and Kim-Park. The Flynn-Wall and Kim-Park methods were the most suitable methods to calculate the activation energy. Samples were exposed to an accelerated degradation test (ADT), under fixed conditions of heat (63±3 o C), humidity (30±4%) and Xenon arc radiation (1.10 W/m 2 ), and the changes in surface morphology and color difference with time were determined. The TLCPs decomposed, discolored and cracked upon exposure to ultraviolet radiation.

“…Because polymer blending may improve the mechanical or thermal properties of polymers, polymer blends have many advantages compared with pure polymers . Polycarbonate (PC) has good mechanical properties, whereas poly(acrylonitrile–butadiene–styrene) (PolyABS) has good chemical resistance.…”

“…The current literature already provides extensive reports on the use of reactive compatibilizers, including anhydrides, for PC–ABS and other similar blends . Recently, there have also been other reports on the use of other compatibilization methods, such as use of (nano)fillers.…”

“…Although PC–PolyABS blends have been investigated by many researchers, studies have rarely been conducted on the correlation between α through the Palierne emulsion model and the compatibility of the PC–PolyABS blends. In this study, we also investigated the α and form relaxation time (τ 1 ) values of the PC–PolyABS blends through the rheological measurements of the PC–PolyABS blends, and the α and τ 1 values were compared with the compatibilizer type and content of the blends.…”

We studied the morphological, mechanical, and rheological properties of polycarbonate (PC) and poly(acrylonitrile-butadiene-styrene) (PolyABS) blends with different types of compatibilizer. Styrene-acrylonitrile-maleic anhydride terpolymer (SAM) was used as a compatibilizer of the blends. For comparison, styrene-acrylonitrile-glycidyl methacrylate terpolymer (SAG) was also used as a compatibilizer. For the PC-PolyABS (70/30 wt %) blends with SAM, the mechanical strength and complex viscosity reached a maximum when the SAM concentration was 5 phr. The mechanical and rheological results of the blend were consistent with the morphological result that the PolyABS domain size reached a minimum when the SAM content was 5 phr. The interfacial tension (a) of the blend was compared with the compatibilizer type and content, which were calculated by the Palierne emulsion model with the relaxation time of the PC-PolyABS blend. The a is consistent with the morphological and mechanical properties of the PC-PolyABS blend. The results of the morphological, mechanical, and rheological properties of the blend suggest that SAM was a more effective compatibilizer than SAG, and the optimum compatibilizer content of SAM was 5 phr.

“…However, most of the polymer blends are found to be incompatible. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] These incompatible polymer blends have poor mechanical and physical properties. In order to improve the mechanical properties of the polymer blends, the compatibilizer has been widely used.…”

Effects of PP-g-MAH on the Mechanical, morphological and rheological properties of polypropylene and poly(acrylonitrile-butadiene-styrene) blends

The effects of maleic anhydride-grafted polypropylene (PP-g-MAH) addition on polypropylene (PP) and poly(acrylonitrile-butadiene-styrene) (ABS) blends were studied. Blends of PP/ABS (70/30, wt%) with PP-g-MAH were prepared by a twin-screw extruder. From the results of mechanical testing, the impact, tensile and flexural strengths of the blends were maximized at a PP-g-MAH content 3 phr. The increased mechanical strength of the blends with the PP-g-MAH addition was attributed to the compatibilizing effect of the PP and ABS blends. In the morphological studies, the droplet size of ABS was minimized (6.6 μm) at a PP-g-MAH content of 3 phr. From the rheological examination, the complex viscosity was maximized at a PP-g-MAH content of 3 phr. These mechanical, morphological and rheological results indicated that the compatibility of the PP/ABS (70/30) blends is increased with PP-g-MAH addition to an optimum blend at a PP-g-MAH content of 3 phr.
