VINYLIDENKLORIDSAMPOLYMERLATEX OCH DESS ANVENDNING SOM BRANDHEMMANDE KLISTERKOMPOSITION

摘要

Improved copolymer latexes and flame-retardant or self-extinguishing adhesive compositions comprising such latexes are provided wherein the copolymer particles of the latexes are beneficially composed of from about 5 to about 60 weight percent of an aliphatic conjugated diolefin; from about 5 to about 55 weight percent of an aromatic vinyl monomer, an acrylate ester or a methacrylate ester; from about 0.5 to about 10 weight percent of an ethylenically unsaturated carboxylic acid; and from about 25 to about 70 weight percent of vinylidene chloride and wherein the copolymer latexes are obtained by first emulsion copolymerizing a first monomer mixture which includes substantially all of the vinylidene chloride, and then emulsion copolymerizing, in the presence of the first copolymerization product, a second monomer mixture which includes substantially all of the aliphatic conjugated diolefin and substantially all of any aromatic vinyl monomer to be employed.
