TRANSPARENT RUBBER MODIFIED STYRENICS COMPOSITIONS

摘要

Transparent ABS compositions useful for extrusion of clear films of a rubbery nature with good adhesion to other polymers and useful for unique molding grade clear compositions with high elongations to failure are provided. The ABS compositions utilize a styrene-butadiene rubber grafted to styrene-acrylonitrile graft phase with a methyl methacrylate and styrene-acrylonitrile rigid matrix phase where the calculated refractive index of the graft phase approximately matches that of the matrix phase in order to achieve transparent blends with ductility.
