Abstract

Absolute compatibilization of immiscible polymer blends via a novel, continuous process, solid-state shear pulverization, and without addition of compatibilizing agents is quantitatively shown for the first time by stability of number-average dispersed-phase domain size to longterm annealing. Compatibilization via pulverization is due to in situ chain scission that is supported by molecular weight analysis of PS before and after pulverization, resulting in polymer radicals that can lead to in situ interfacial block copolymer formation.
