First Claim
1. A paste capable of being gelled at low temperatures consisting essentially of:
- 100 parts by weight of a pastable emulsion polymer comprised of carboxylated monomer/vinyl chloride/vinyl acetate terpolymer having improved strength of adhesion produced by emulsion copolymerization and containing, per polymer weight,from 60% to 98% by weight of vinyl chloride monomer units,from 1% to 29% by weight of vinyl acetate monomer units, andfrom 1% to 15% by weight of carboxyl-containing monomer units selected from the group consisting of olefinically-unsaturated monocarboxylic acids, monoallyl esters of non-ethylenically-unsaturated dicarboxylic acids and monovinyl esters of non-ethylenically-unsaturated dicarboxylic acids, and recovered by spray drying or roll drying,from 10 to 100 parts by weight of at least one plasticizer selected from the group consisting of esters of alkanols having from 6 to 18 carbon atoms or phenols or alkylphenols having from 1 to 18 carbon atoms in the alkyl with dicarboxylic acids or phosphoric acid,from 0 to 10 parts by weight of heat stabilizers andfrom 0 to 10 parts by weight of additives selected from the group consisting of dyestuffs, pigments, fillers and UV-absorbers.

Abstract
A pastable emulsion polymer comprised of carboxylated monomer/vinyl chloride/vinyl acetate terpolymer having improved strength of adhesion produced by emulsion copolymerization and containing, per polymer weight,
from 60% to 98% by weight of vinyl chloride monomer units,
from 1% to 29% by weight of vinyl acetate monomer units, and
from 1% to 15% by weight of carboxyl-containing monomer
units selected from the group consisting of olefinically-unsaturated monocarboxylic acids, monoallyl esters of non-ethylenically unsaturated dicarboxylic acids, and monovinyl esters of non-ethylenically-unsaturated dicarboxylic acids. The terpolymers are manufactured by the copolymerization of vinyl chloride, vinyl acetate, olefinically-unsaturated monocarboxylic acids and/or monoallyl esters and/or monovinyl esters of non-ethylenically unsaturated dicarboxylic acids in an aqueous emulsion. The pastable terpolymers, after empasting are used for coating flexible sheet-like articles.
