COPOLYESTER POLYOLS, PREPOLYMERS, AND POLYURETHANE ELASTOMERS FORMED THEREFROM AND PROCESSES FOR MAKING SAME

摘要

Polyurethane elastomers formed from prepolymers derived from copolyesterpolyols. The copolyester polyols have segments derived from one or more polyesters and caprolactone or polycaprolactone. The polyurethane elastomers have good hardness stability at temperatures ranging from 0°C to 30°C and preferably have good hydrolytic stability.
