ABSTRACT:
Elastomers are plasticized with a polymerizable monomer, in homogeneous admixture therewith, by adding the monomer to a latex of the elastomer, free of polymerization initiator, followed by coagulation of the monomer and polymer solids. The coagulated solids recovered from the latex may be compounded with a polymerization initiator for the monomer and a vulcanizing agent for the polymer and, optionally, an inorganic filler, and shaped into the desired product form. Polymerization of the polymer and vulcanization of the elastomeric polymer are initiated after shaping.
