PROCESS FOR PRODUCING COPOLYMER LATEX AND USE THEREOF.

摘要

A process for producing copolymer latex by the emulsion polymerization of an aliphatic conjugated diene monomer and another monomer copolymerizable therewith in the presence of a cyclic unsaturated hydrocarbon having one unsaturated bond in the ring, characterized in that the addition of a monomer mixture containing the diene monomer is followed by the addition of another monomer mixture free from the diene monomer, or that part of a chain transfer agent is added after the addition of the monomers. The obtained latex is useful as an adhesive composition, paper coating composition, carpet backing adhesive composition, rock fiber base adhesive composition, gravure paper coating composition, color developing agent composition for pressure-sensitive paper, and the like.
