ABSTRACT:
Process for the preparation of latices of vinyl acetate polymers. Vinyl acetate is polymerized by itself or mixed with at least one copolymerizable monomer, in aqueous emulsion, in the presence of an initiator, an emulsifier and a protective colloid comprising a water-soluble polymer (a) containing at least one monomer of acrylamide, methacrylamide, or substituted or unsubstituted N-alkyl derivatives of acrylamide or methacrylamide and a water-soluble polymer (b) of ethylene glycol, the polymer (b) having a molecular weight between 1,000 and 50,000. The latices may be applied as binders in the manufacture of paints, glues, paper, textiles, floor coverings and mortar additives.
