Title:
ADHESIVE COMPOSITION OF VINYL ACETATE-BASED RESIN EMULSION
Document Type and Number:
Japanese Patent JP3290499
Kind Code:
B2
Abstract:
PURPOSE: To obtain an adhesive composition consisting mainly of vinyl acetate- based resin emulsion useful for woodworking, etc., having excellent viscosity stability, slight occurrence of coarse particles, improved initial polymerizability and mechanical atability.
CONSTITUTION: A vinyl acetate-based resin emulsion as a main component is obtained by subjecting a vinyl acetate monomer to emulsion polymerization by using a copolymer of an α-olefin and an unsaturated carboxylic acid or its derivative adjusted to pH 4.8-7.5 by adding a basic substance as a protective colloid to give the objective composition. Preferably the vinyl acetate monomer is initially polymerized, ammonia is added to the polymerization system to adjust pH4.8-7.5 and emulsion polymerization is carried out.
