Effect of Reactive Compatibilization on Localization of PS Particles in Co-continuous PP/PE Blends

In this work in-situ reactive compatibilization of PP/PE/PS ternary blends was studied. . Effect of compatibilization via Friedel-Crafts alkylation reaction was investigated by means of dynamic rheometery measurements and SEM analysis. It was shown that while the PS particles had more tendency to PP phase than that of PE phase, reactive compaibilization using AlCl3 catalyst increased the affinity of PS droplets to PP/PE interface, which was related to the effectively generation of PE-g-PS copolymer. Compatibilized blends showed finer dispersed morphology of PS particles.
