Abstract

PURPOSE: To prepare a latex without causing coarse particles stably and economically, by dispersing an ethylene-copolymer containing an alkali metal, having a moderate wettability with hot water and the heat of fusion, in warm water.
CONSTITUTION: An ethylene copolymer consisting of ethylene-unsaturated carboxylic acid or ethylene-unsaturated carboxylic acid-polymerizable ester monomer, wherein part or all of the carboxylic acid is an alkali metal salt, is dispersed in warm water at 60W120°C to give the objective latex. The copolymer has a wettability with hot water at 95°C of 5W200%, preferably 5W100%, and the heat of fusion of 2.0W11.0 cal/g, preferably 3W10cal/g.
EFFECT: Water, oil, and chemical resistance, and heat sealing properties, and adhesion to other substrates can be imparted to paper aluminum foils, and synthetic resin films by coating the latex thereon.
