摘要
Elastomers with improved physical properties, particularly hardness, resilience, tear strength, and compression set, may be prepared by the chain extension or moisture cure of isocyanate-terminated prepolymers prepared from a polyol component comprising a high molecular weight, low unsaturation polyoxypropylene diol and a low molecular weight diol. The elastomers are useful for applications such as rollers and other applications for which these physical properties are important.
