ABSTRACT:
Compatibilized blends of an isoolefin polymer and an unsaturated diene polymer are prepared by utilizing a compatibilizing agent comprising a block/graft copolymer containing poly- or copoly-isoolefin segments and C4to C6alkyl-substituted styrene polymer segments, such as poly(t-butylstyrene) segments.
