Abstract
A copolymer latex obtained by emulsion-polymerization of 45 to 85% by weight of a conjugated diene monomer, 0.1 to 25% by weight of an ethylenically unsaturated acid monomer, 10 to 45% by weight of a vinyl-pyridine monomer and 0 to 30% by weight of another monomer copolymerizable with these monomers. The surface of the latex particles contains the carboxy groups in an amount of at least 0.01 milliequivalent per gram of the copolymer. An adhesive composition comprising the copolymer latex is useful for boding fibers, particularly polyester fibers, to rubber with a high adhesion strength.
