ABSTRACT:
The elongation at fail and toughness of rubber reinforced polystyrene and ABS type polymeric polyblends are improved without loss of tensile strength by the addition of a liquid polymer of a conjugated diene monomer having a molecular weight of from about 1,000 to 10,000. The liquid polymers may be incorporated during any stage of the process for preparing the polymeric polyblend.
