Compositions comprised of ultra-high molecular weight polyethylene slurried in a styrene monomer containing a styrene crosslinker and a free radical catalyst are disclosed. These slurries are subjected to heating in a mold whereby the polyethylene phase is dissolved in the styrene monomer and the styrene monomer is polymerized to form a shaped article. The polystyrene/polyethylene product has unique properties.

UHMWPE/styrenic molding compositions with improved flow properties and

Novel thermoplastic compositions are provided comprising a blend of a polyindane resin and an engineering thermoplastic such as polyphenylene ethers, polysulfones, polycarbonates, polyether ether ketones, polyarylates, polyamides, polyimides and polyphenylene sulfides. Blends of thermoplastic block copolymers with polyindane resins are also provided. These blends provide improved processability with good physical properties including high impact strength and high heat distortion temperature.
