The polyimides have inherent viscosities that range from 1.55 to 2.05 dL/g in NMP at 30 degrees C. These polymers showed glass transition temperatures between 188 and 268 degrees C, and an initial decomposition temperature from 421 to 502 degrees C with a 10% mass loss occurring from 480 to 547 degrees C in air.eninfo:eu-repo/semantics/closedAccesspolyimidesfunctional polymersmetal containing polymersseleniumArticle15226927910.1007/s10904-005-5544-22-s2.0-22144462881Q2WOS:000230299500007Q2
