Phase behavior in blends of poly(styrene-co-o(p)-bromostyrene) and phenylsulfonylated poly(2, 6-dimethyl-1, 4-phenylene oxide) copolymers
Random copolymers of styrene with ortho- or para-bromostyrene differ substantially in their blend behavior with partially sulfonylated poly(2, 6-dimethyl-1, 4- phenylene oxide) (SPPO). Copolymers of styrene with ortho-bromostyrene exhibit a very narrow window of miscibility in comparison to styrene - para-bromostrene copolymer blends with SPPOs. The experimentally obtained results can be accounted for on the basis of individual segmental interaction parameters by applying mean field theory.
