Elastomeric polyurethanes with improved properties based on crystallizable polyols in combination with low monol polyoxypropylene polyols |
摘要 |
Polyurethane elastomers of improved elongation, tensile strength and other physical properties are prepared from a polyol component containing a crystallizable polyol and from 5 to 35 equivalent percent of a low monol polyoxypropylene polyol by one-shot, quasiprepolymer, and preferably, by prepolymer techniques involving chain extension with an aliphatic diol or aromatic amine. |
