    Abstract: A polymer composition may include polyolefin having a molecular weight distribution of greater than or equal to 8 as measured by GPC and a metallic acrylate salt. The polymer composition may be characterized by one or more of: a melt flow rate of from 0.1 g/10 min to 10 g/10 min; a melt flow viscosity between 2,000 Pa·s and 6,000 Pa·s; a die swell of between 2 and 8; and a die swell characteristic time of between 0.3 seconds and 1.2 seconds. The polymer composition may be in the form of foam. A process of forming foam may include supplying polymer composition including metallic acrylate salt and polyolefin resin, and mixing the polymer composition with foaming agent. A foam may include a polymer composition that includes polyolefin and polar polymer and does not include an ionomer. The foam may have a foam density of less than 0.25 g/cc.

    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.
