Abstract

Block copolyimides were synthesized from 3,3 prime ,4,4 prime benzophenonetetracarboxylic dianhydride by reaction with 4,4 prime -methylenedianiline and poly(dimethylsiloxane) diamines. Aromatic diamineterminated poly(dimethylsiloxanes) were prepared by the base-catalyzed equilibration of octamethylcyclotetrasiloxane with 1,3-bis(4-aminophenoxypropyl) tetramethyldisiloxane. The amount of poly(dimethylsiloxane) incorporated in the copolyimides was 5-15 wt %. The selected molecular weight of poly(dimethylsiloxane) diamine was 4500.
