Abstract

Physical blends of bisphenoI-A polycarbonate (PC) and a polyarylate (PAr) exhibit by thermal analysis two amorphous phases: a pure PC phase and a PAr-rich miscible mixed phase. On controlled thermal treatment, transreaction between PC and PAr takes place mainly in the mixed phase, producing a new copolymer. Reaction progression from block to random copolymers has been traced by DSC, 13C NMR and GPC. The final product of transreaction is an amorphous copolymer showing a single Tg depending on the original binary composition.
