Abstract

Polymeric anhydrides having the structure <FORM:0838986/IV (a)/1> in which R is a radical from the group hydroxyl, alkyl, carbonyloxy, aryl carbonyloxy and halogen, n being an integer greater than 10, are prepared by (1) the interaction of isophthalic acid with the anhydride of a monofunctional carboxylic acid, such as acetic or benzoic acid, or an acid chloride, such as acetyl chloride; and (2) the reaction of isophthaloyl chloride with less than the stoichiometric amount of water, or with a carboxylic acid or a metal salt thereof, such as a salt of isophthalic acid. The products may be modified by copolymerization with other anhydrides e.g. terephthalic anhydride. The polymers and copolymers of the invention are useful for the production of films and fibres which can be made either from the molten polymers or their solutions in e.g. cyclohexanone.
