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 cristallizable polyol and from 5 to 35 equivalent percent of a low monol polyoxypropylene polyol by one-shot, quasi-prepolymer, and preferably, by prepolymer techniques involving chain extension with an aliphatic diol or aromatic amine.
