Claims
- 1. A mixture of copolymers formed for use as coating for rubber articles said mixture comprising a first emulsion copolymer which is the reaction product formed by copolymerizing a first monomer mixture comprising styrene, butyl acrylate, methyl acrylate, methacrylic acid, acrylic acid and at least one copolymerizable silicone oligomer in emulsion, said first emulsion copolymer having a glass transition temperature less than about 0.degree. C. and a second emulsion copolymer which is the reaction product of a second monomer mixture comprised of styrene, butyl acrylate, methylacrylate, methacrylic acid, acrylic acid and at least one copolymerizable silicone oligomer, said second emulsion copolymer having a glass transition temperature of from about 0.degree. C. to about 100.degree. C., said mixture of first and second acrylic based emulsion copolymers being formed by sequential emulsion polymerization in the presence of at least two anionic surfactants and when deposited from suspension on a rubber article form when dry a non-tacky coating.
