Thermoplastic imide polymers prepared from a dianhydride monomer containing imide linkages and at least two cyclic anhydride groups and an aromatic diamine such as 4,4′-diaminodiphenyl ether. Comonomers such as 3,4:3′, 4′-benzophenonecarboxylic dianhydride may be added. Preferably said dianhydride monomer containing imide linkages is made by reacting 4-aminophthalic acid with a dianhydride containing at least two cyclic anhydride groups, preferably in the ratio of about 2:1. Preferably said imide polymer is made by first forming a solution containing the diamine and adding the dianhydride monomer containing imide linkages while the temperature of the solution is maintained between 50°and 120°C. and most preferably at 110°C.

A polymer containing imide linkages corresponding to that prepared by reacting a dianhydride component comprising (A) an aromatic dianhydride monomer containing two imide linkages, two terminal cyclic anhydride groups and two trivalent benzene radicals, the carbonyl groups of a cyclic anhydride and
A polymer containing imide linkages corresponding to that prepared by reacting a dianhydride component comprising (A) an aromatic dianhydride monomer containing two imide linkages, two terminal cyclic anhydride groups and two trivalent benzene radicals, the carbonyl groups of a cyclic anhydride and a nitrogen of an imide linkage attached to each of said radicals, the former attached to 1,2-positions of the radical, the latter attached to the 4-position of the radical and (B) an aromatic diamine. A polymer containing imide linkages as claimed in claim 3 wherein said dianhydride containing two cyclic anhydride groups is selected from the group consisting of: 2,3:6,7-naphthalene tetracarboxylic dianhydride, 1,8:4,5-naphthalene tetracarboxylic dianhydride 1,2:5,6-naphthalene tetracarboxylic dianhydride, 3,4:3′,4′-diphenyltetracarboxylic dianhydride, 2,3:2′,3′-diphenyltetracarboxylic dianhydride, bis(3,4-dicarboxyphenyl) methane dianhydride, 2,2-bis(3,4-dicarboxyphenyl) propane dianhydride, bis(3,4-dicarboxyphenyl) sulfone dianhydride, and bis(3,4-dicarboxyphenyl) ether dianhydride.
