Polyoxymethylene/thermoplastic polyurethane/amorphous thermoplastic polymer blends.

摘要

This invention relates to blends containing (a) 40-98 weight percent polyoxymethylene, (b) 1-40 weight percent thermoplastic polyurethane, and (c) 1-59 weight percent of at least one amorphous thermoplastic polymer, said blends being characterized as having better mold shrinkage than polyoxymethylene/thermoplastic polyurethane compositions and also having a useful balance of physical properties, such as stiffness, elongation, and toughness.
