ABSTRACT:
A process for the production of a nonaqueous stable emulsion feedstock comprising a rubber, a block copolymer having at least one component miscible with the rubber and at least one component miscible with the monomer, and at least two unsaturated organic monomers capable of free radical polymerization is disclosed. At least one of the monomers must be miscible with the rubber and the mixture of the monomers is substantially a nonsolvent for the rubber. The block copolymer maintains the rubber or rubber-rich particles in emulsified form within the mixture of monomers. In general, the process comprises (1) mixing the rubber, block copolymer and at least a portion of the rubber miscible monomers to form a first nonaqueous solution, (2) mixing the remaining monomers and the remaining portion of the rubber miscible monomers to form a second solution, and (3) combining the two solutions to form the nonaqueous stable emulsion feedstock. A process for polymerizing this feedstock material and the polymerization product produced thereby is also disclosed.
