Abstract
Self-stabilized resin latexes are provided which contain carboxylate salts of post-chlorinated ethylene copolymers having chlorine contents of 20-60 weight percent. The ethylene copolymer salts are derived from ethylene/acrylic acid or ethylene/methacrylic acid copolymers containing 1.5-12 mole percent copolymerized units of acrylic or methacrylic acid. The latexes are particularly useful for preparing resorcinol formaldehyde adhesives.
