ABSTRACT:
The specification discloses a method for forming a rubber concentrate which can be incorporated in relatively high percentages into rubber reinforced polymers without adversely affecting processability. A rigid polymer forming monomer system is polymerized in the presence of a mixture of a low molecular weight rubber (weight average molecular weight of from about 2,000 to about 50,000) and a higher molecular weight rubber (weight average molecular weight of from about 100,000 to about 400,000). The resulting rubber concentrate can be incorporated into a rigid polymer blend which is compatible with the rigid polymer forming monomer phase of the rubber concentrate. The resulting new composition has significantly improved impact strength and acceptable processability.
