Liquid mixture comprising a polya ethylenically unsaturated aet preferential poly epoxide poly ether

摘要

Liquid mixtures which are curable by exposure to ultraviolet light when appropriately photosensitized are provided by etherifying a polyepoxide with an at least 25% stoichiometric excess of an hydroxy alkyl ester of an alpha, beta-monoethylenically unsaturated monocarboxylic acid, expecially hydroxy ethyl acrylate. The unreacted hydroxy alkyl ester is then consumed by reaction with at least 1 molar equivalent of a monoanhydride, such as a monoepoxide, a lactone, or a monoisocyante.
