ABSTRACT:
Latices of vinyl acetate polymers comprising particles having an average diameter between 0.05 and 1 .mu.m and being present in the latex at a concentration of between 10 and 70% by weight. The polymers have a glass transition temperature between -20.degree. and 50.degree. C. The latices also contain a protective colloid comprising a water-soluble polymer (a) containing at least one monomer selected from the group consisting of N-methylolacrylamide and N-methylolmethacrylamide and a water-soluble polymer (b) of ethylene glycol, the polymer (b) having a molecular weight between 1,000 and 50,000.
The latices are prepared by polymerization in aqueous emulsion, in the presence of both an initiator and the above-reference protective colloid. The latices may be applied as binders in the manufacture of paints, glues, paper, textiles, floor coverings and mortar additives.
