Abstract
Elastomers with improved physical properties, particularly hardness and rebound, may be prepared by the diamine chain extension or moisture cure of low isocyanate group content, toluene diisocyanate-based 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 where hardness and rebound are important.
