Patent ID: 8541108

Claim:
A fuser member comprising: a substrate layer comprising a polyimide polymer formed from a reaction between a polyamic acid and a hydroxyl terminated polybutadiene, wherein the polyamic acid is selected from the group consisting of pyromellitic dianhydride/4,4′-oxydianiline, pyromellitic dianhydride/phenylenediamine, biphenyl tetracarboxylic dianhydride/4,4′-oxydianiline, biphenyl tetracarboxylic dianhydride/phenylenediamine, benzophenone tetracarboxylic dianhydride/4,4′-oxydianiline and benzophenone tetracarboxylic dianhydride/4,4′-oxydianiline/phenylenediamine, wherein the polyimide polymer and the hydroxyl terminated polybutadiene are present in a weight ratio of about 99.9 /0.1 to about 99/5 and wherein the polybutadiene crosslinks with the polyimide polymer.
