Imide polymers

Claim 1

A blend of at least one thermoplastic polymer and a second polymer containing glutarimide units wherein the degree of imidization, by weight, on said polymer is from about 1% to about 95%, and the degree of imidization and the acid and anhydride functionality on said polymer, expressed in milliequivalents per gram of total imidizable and imidized polymer units are as set forth below; ______________________________________ when the degree of imidizaton the milliequivalents of acid on said polymer is and anhydride per gram are ______________________________________ from about 1% to about 10% 0 to about 0.20 above about 10% to about 20% 0 to about 0.28 above about 20% to about 30% 0 to about 0.32 above about 30% to about 40% 0 to about 0.31 above about 40% to about 50% 0 to about 0.28 above about 50% to about 60% 0 to about 0.28 above about 60% to about 70% 0 to about 0.27 above about 70% to about 80% 0 to about 0.28 above about 80% to about 90% 0 to about 0.33 and above about 90% to about 95% 0 to about 0.40. ______________________________________
