Abstract
New emulsion polymers comprising vinyl acetate-acrylate or methacrylate emulsion polymer containing in the polymer an .alpha.,.beta.-ethylenically unsaturated acid ester of a polyol. For example, pentaerythritol tri- and tetra-acrylate, trimethylolpropane triacrylate, hexanediol diacrylate, etc.
Claims9
A latex composition comprised of an emulsion polymer of vinyl acetate with from about 5% to about 50% by weight of alkyl acrylate or methacrylate based on the total weight of vinyl acetate and alkyl acrylate or methacrylate and from about 2% to about 10% by weight, based on the total weight of said polymer, of an acrylic or methacrylic acid ester of a polyol in which at least two hydroxyl groups are esterified.
A latex coating composition comprising an emulsion polymer of vinyl acetate with from about 5% to about 50% by weight of alkyl acrylate or methacrylate based on the total weight of vinyl acetate and alkyl acrylate or methacrylate and from about 2% to about 10% by weight, based on the total weight of said polymer, of an acrylic or methacrylic acid ester of a polyol in which at least two hydroxyl groups are esterified.
A latex paint composition comprising an emulsion polymer of vinyl acetate with from about 5% to about 50% by weight of alkyl acrylate or methacrylate based on the total weight of vinyl acetate and alkyl acrylate or methacrylate and from about 2% to about 10% by weight, based on the total weight of said polymer, of an acrylic or methacrylic acid ester of a polyol in which at least two hydroxyl groups are esterified.
