Abstract
Process for the preparation of latices of vinyl acetate/olefin copolymers. Vinyl acetate is copolymerized with at least one olefin and, if desired, at least one other 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 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.
