  • Polyol blends and polyurethane prepared therefrom
    Patent number: 4101439
    Abstract: A poly(oxyethylene-oxypropylene)glycol and poly(sutramethylene ether)glycol are blended together and the resulting blend and a chain extender are reacted with an organic diisocyanate under conditions which produce a thermoplastically processible polyurethane elastomer. The polyurethane elastomer can be used to advantage for making the sheath of a hydraulic hose.
    Type: Grant
