Abstract:
A high impact polystyrene (HIPS) is made from styrene monomer and 3 to 20 wt % of an elastomeric component phase including polybutadiene rubber and styrene butadiene copolymer. The HIPS has a 60 degree gloss of 90 or more, a Gardner drop of at least 10 in-lb, and an Izod impact strength of 1.8 ft-lb/in or more. The HIPS can have salami morphology with rubber particle size between 1 and 1.3 microns.
