Abstract
Latices of particles of vinyl acetate/olefin copolymers. The particles have an average diameter between 0.05 and 1 .mu.M. The copolymers have a glass transition temperature between -30.degree. and 50.degree. C. The particles are present in the latices in a concentration between 10 and 70% by weight. The latices 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, wherein polymer (b) has a molecular weight of between 1,000 and 50,000. The latices are prepared by polymerization in aqueous emulsion, in the presence of an initiator and the above-described protective colloid. The latices may be applied as binders in the manufacture of paints, glues, paper, textiles, floor coverings and mortar additives.
