Disclosed is a novel polybutadiene or butadiene-styrene copolymer based gum plastic having excellent impact strength and a method for its preparation. The use of small particle size (SPS) spine latex in a latex-suspension process gives unexpectedly good properties by yielding an ABS with at least about 85% of the rubber present as particles within a specified and relatively narrow size range, i.e., 0.04-0.25 mu and having a number average particle size less than 0.14 mu . In the method of preparation, the latex spine and monomers are converted directly to the final product by a conventional suspension process. |
