Abstract

PURPOSE: To obtain an ethylene-vinyl ester copolymer emulsion with excellent processability and coating property, by the emulsion copolymerization of ethylene with a vinyl ester by use of a specified PVA copolymer as a protective colloid.
CONSTITUTION: A PVA copolymer is obtd. by the copolymerization of (A) 0.2W 10mol% at least one monomer selected from a 6C or higher fatty acid vinyl ester, a 6C or higher alkyl vinyl ether and a 6C or higher α-olefin, (B) 0.5W70mol% ethylenically unsaturated carboxylic acid (a lower alkyl ester) or acid anhydride (e.g., maleic anhydride) and (C) vinyl acetate in the presence of a radical polymn. catalyst, followed by the saponification of the copolymer obtd. Then an ethylene- vinyl ester copolymer emulsion is obtained by the emulsion copolymerization of a 1W18C fatty acid vinyl ester under an ethylene pressure of 5W150kg/cm2, by use the PVA copolymer as a photective colloid.
