ABSTRACT:
Rubber concentrates for use in reinforcing acrylonitrile and styrene-containing polymers are prepared by graft polymerizing an acrylonitrile-styrene polymer on a rubber latex wherein a portion of the polymer is chemically combined with the rubber and a portion of the acrylonitrile-styrene polymer is not chemically combined. The uncombined or matrix polymer is of relatively low molecular weight.
