High resilience, high clarity polyurethane elastomer

摘要

A polyurethane elastomer possessing high resilience and high clarity is obtained by subjecting to polyurethane elastomer-forming conditions a polyurethane elastomer-forming reaction mixture comprising: a) an isocyanate selected from the group consisting of diphenyl methane diisocyanate, isocyanate obtained from the reaction of polyol with MDI and mixtures thereof; b) at least one polyol; and, c) at least one diol chain extender of the general formula:HO-(CH2)x-OHwherein x is an integer from 5 to about 16.
