POLYURETHANE WITH IMPROVED ABRASION RESISTANCE, THE METHOD FOR PREPARING THE SAME AND USE THEREOF

摘要

The present invention pertains to a polyurethane with improved abrasion resistance. The reactive component for preparing the polyurethane includes a polybutadiene, wherein the polybutadiene comprises 1,2-butene structure unit, 2,3-(cis) butene structure unit and 2,3-(trans) butene structure unit, wherein the amount of the 2,3-(trans) butene structure unit is more than the amount of the 2,3- (cis) butene structure unit. The polyurethane presented in this invention possesses improved abrasion resistance and good surface quality.
