Abstract

The subject-matter of this Specification is almost wholly identical with that described in Specification 928,309, but the claims are directed to a method of continuously coagulating rubbery polymer latices containing dispersed pigment and/or reinforcing agent (such as carbon black) by mixing a latex of the rubbery polymer with an aqueous suspension of pigment and/or reinforcing agent and continuously coagulating the resultant mixture in a continuous operation by addition of fresh coagulant substantially free of recycled serum to produce coagulum of the rubbery polymer containing dispersed pigment and/or reinforcing agent, the resultant coagulum then being separated from the serum. Specification 903,245 also is referred to.
