ABSTRACT:
An aqueous polyvinyl ester dispersion having a solids content of 40 to 70 percent by weight and containing 3 to 15 percent by weight (relative to the total amount of polyvinyl ester and additive) of a polyvinyl alcohol and 5 to 60 percent by weight (relative to the total amount of polyvinyl ester and additive) of a waxy, fatty or oily additive, has excellent adhesive properties. It is prepared by emulsion polymerization of a vinyl ester, if appropriate together with comonomers, in the presence of the said additive or by subsequent distribution of the additive in the dispersion resulting from the emulsion polymerization. The dispersion is particularly suitable for the preparation of adhesives for cellulose-containing materials.
