Polyester imides and method for producing same |
| abstract |
The invention relates to a method of producing polyester imides of the formula ##STR1## by reacting tetracarboxylic acid dianhydrides of the formula ##STR2## with N,N'-bis(Ω-hydroxyalkyl)dicarboxylic acid diamides of the formula, HO--Z--NH--CO--B--CO--NH--Z--OH, where n A represents a quadrivalent aromatic group with 6-32 C atoms, wherein up to 40% of A may be replaced by a quadrivalent aliphatic group with up to 16 C atoms, n B represents a divalent aliphatic or aromatic group with up to 14 C atoms, n Z represents an alkylene group with 2-3 C atoms, and n n is a number from 3 to 500. |
