ABSTRACT:
The invention relates to an emulsion polymerization process for preparing polymeric polyblends having rubber phases with high levels of grafted monomers providing polyblends with superior extruded glass and toughness. Diene rubber particles in latices are grafted with a monomer formulation of alkenyl aromatic and alkenyl nitrile monomers having present about 1 to 30% by weight of a myrcene triunsaturated aliphatic C.sub.10 H.sub.16 hydrocarbon. The myrcene unexpectedly increases the graft efficiency of the alkenyl aromatic and alkenyl nitrile monomers substantially as a superstrate on the rubber substrate particles such that a polyblend of a matrix phase polymer of said monomers having said grafted rubber dispersed therein has superior toughness and gloss.
