Thermoplastic polyblends of aromatic polycarbonates and thermoplastic polyurethanes.

摘要

Binary thermoplastic polyblends consisting essentially of from 50 to 95 weight percent thermoplastic aromatic polycarbonate and from 5 to 50 weight percent polycaprolactone polyol-based thermoplastic polyurethane (TPU) having a Shore Hardness of from 70A to 70D exhibit improved hydrocarbon solvent resistance over polycarbonate resins.
