Radiation process for producing a reactive aqueous emulsion

摘要

A process for producing a reactive aqueous emulsion comprising dispersing a monomer mixture of (a) 65.0 - 98.8% by weight of radical polymerizable hydrophobic ethylenic unsaturated monomer having one ethylenic unsaturated bond, (b) 1.0 - 30.0% by weight of radical polymerizable ethylenic unsaturated monomer having a glycidyl group and (c) 0.2 - 5.0% by weight of a radical polymerizable ethylenic unsaturated monomer having a carboxylic group in water by virtue of a restricted amount of surface active agent and irradiating with an ionizing radiation for a total dose of more than 0.01 Mrad at temperatures ranging from -5 DEG C. to 50 DEG C. This reactive aqueous emulsion does not contain low-molecular water-soluble compounds such as a radical polymerization initiator, a pH regulator, etc. and can form a film having improved properties.
