Abstract

Thermoplastic molding compositions are made from a blend of high molecular weight and low molecular weight polycaprolactones. The blends have lower viscosity, and can have higher modulus, than a composition containing only high molecular weight polycaprolactone. The blends are especially useful for dental impressioning.
