Abstract
Physical properties of polymer resins, particularly amorphous resins such as ABS or SAN copolymers, are markedly improved by dispersing therein a filler-reinforced engineering thermoplastic polyurethane.
Claims9
A composition comprising a dispersion of a filler-reinforced engineering thermoplastic polyurethane in an amorphous or a crystalline polymer resin wherein the engineering thermoplastic polyurethane is characterized by having a Tg of greater than 50° C.
A composition comprising a dispersion of a filler-reinforced engineering thermoplastic polyurethane in an amorphous or crystalline polymer resin wherein the engineering thermoplastic polyurethane is characterized by having:
- a) a Tg of greater than 50° C.;
- and b) a hard segment that constitutes about 100 percent by weight of the engineering thermoplastic polyurethane.
