Abstract:
The melt of polyvinyl aromatic polymers comprising from 10 to 45 weight % of star branched polymer prepared using a combination of thermal and tetra functional peroxide initiation has an improved melt strength permitting better foam formation for extrusion foam blown with conventional blowing agents and inert gases including CO and an improved tensile strength for oriented polystyrene (OPS) articles, e. g. blown film or extruded sheet.

Abstract:
Orthopaedic structures, and processes for making the same, are provided in which the orthopaedic structure comprises a polymeric material which contains a block copolymer having grafted to it styrene, an alkyl acrylate and optionally methyl methacrylate. The orthopaedic structures are substantially transparent, formable and reformable at temperatures of about 45. degree. to about 65. degree. C. and are essentially rigid at ambient temperatures.
