Abstract

A method has been worked out for the synthesis of α,ω-(3-aminophenoxy) terminated poly[oxy(dimethylsilyl)-1,4-phenylene(dimethylsilylene)] oligomers with controlled molecular weight. From these oligomers were synthesized polyimide-polysiloxane block copolymers via a transimidization route, with polyimide moieties based on 2-aminopyridine terminated 5,5′-oxybis-1,3-isobenzofuranedione-4,4′-[1,4-phenylenebis(1- methylethylidene)]bisaniline oligomers. The copolymers obtained show higher thermooxidative stability in comparison with copolymers having siloxane moiety based on α,ω-aminopropyl or α,ω-arylamine terminated poly(dimethylsiloxane) oligomers.
