<p>A polymer composition obtained by mixing, in an emulsion state,
(A) from 20 to 90% by weight (as solid content of polymer) of an emulsion of polymer component (A) which is a polymer of a vinyl monomer and has a glass transition temperature of higher than 20°C, a gel content of higher than 10% and a solubility parameter of from 8.0 to 11.0 (cal/cc)<Sup>1/2</Sup> and which has a weight average molecular weight, based on polystyrene, of at least 1.5 x 10⁵, and
(B) from 10 to 80% by weight (as solid content of polymer) of an emulsion of polymer component (B) which is a homopolymer of an acrylate monomer, a copolymer of acrylate monomers or a copolymer of an acrylate monomer with other copolymerizable monomer and has a glass transition temperature of not higher than 20°C, a gel content of not higher than 70% and a solubility parameter of from 8.4 to 9.8 (cal/cc)<Sup>1/2</Sup>,
and separating the polymer from the emulsion mixture. </p> |
