Abstract

A method of making an ester-imide resin according to any of Claims 1 to 4 of the parent Specification, wherein the ester imide formed contains aliphatic residues derived from one or monocarboxylic acids having 6 to 24 carbon atoms, comprises introducing said residues by reacting the ester-imide resin or one of the starting materials for the preparation thereof with monocarboxylic acid or acids. Specified monocarboxylic acids are those derived from tallow, olive, soya bean, linseed and coconut oil and 2-ethylhexanoic acid. The examples describe the preparation of modified polyestermides from: (1) a mixed ester derived from dimethyl terephthalate, glycerol, butanediol and coconut oil and a diimide made from trimellitic anhydride and 4 : 41-diaminodiphenylmethane; (2) a condensate from glycerol, natural fatty acids, isophthalic acid and butanediol, 4 : 41-diaminodiphenyl methane and trimellitic anhydride, and (3) a diimide made from 4 : 41-diaminodiphenyl methane and trimellitic anhydride, coconut oil and glycerol. The products of the examples are soluble in benzene hydrocarbons, chlorinated hydrocarbons, ketones or esters and may be reacted with cross-linking agents for example amino - triazine - alcohol - formaldehyde condensates and stabilized polyisocyanates.
