ABSTRACT:
High-impact poly(styrene) resins modified with small-particle-size, multi-stage impact modifiers having a crosslinked poly(butadiene) core and a poly(styrene) or other vinylaromatic polymer shell show an improved balance of impact strength, stiffness and surface gloss, and an improved resistance to environmental stress crazing, when compared to conventional high-impact poly(styrene).
