Mechanical, thermal, theological and morphological behavior of poly (trimethylene terephthalate)/high impact poly (styrene) blends compatibilized with poly (styrene-co-ethylene-co-butylene-co- styrene)-g-maleic anhydride

摘要

The development of polymer blends, composites and laminates is of great economic importance for the plastics industry and for other industries where the use of such products is becoming increasingly common. Advanced polymer modification techniques have grown in importance during the last two decades as the "point of diminishing returns" has been approached in improving the performance/price balance by altering just the chemical structures of polymers. Most pairs of polymers are immiscible with each other. Even worse is the fact that they also have less compatibility than would be required in order to obtain the desired level of prop-erties and performance from their blends. Compatibilizers are often used as additives to improve the compatibility of immiscible polymers and thus improve the morphology and resulting properties of the blend.
