COPOLYMER LATEX FOR ADHESIVES

摘要

A copolymer latex for adhesives which comprises (A) 50 to 90 wt% (in terms of solid matter) of a copolymer latex obtained by emulsion polymerization of a monomer composition (a) that comprises 35 to 75wt% of a butadinene monomer, 10 to 30wt% of a vinylpyridine monomer, and 10 to 55wt% of a styrene monomer and (B) 10 to 50wt% (in terms of solid matter) of a copolymer latex obtained by emulsion polymerization of a monomer composition (b) that comprises 3 to 25wt% of a butadiene monomer, 0 to 5wt% of a vinylpyridine monomer, 55 to 97wt% of a styrene monomer, 0 to 10wt% of an ethylenically unsaturated carboxylic acid, and 0 to 20wt% of one or more other copolymerizable monomers.
