Modified polyurethane material and method for manufacturing the same

Abstract

A modified polyurethane material and a method for manufacturing the same are provided. A dianhydride is added into an aliphatic diisocyanate to form a liquid reactant. A solvent is absent from the liquid reactant. An oligomerization is implemented onto the liquid reactant so as to form an oligomer having a terminal isocyanate group. A polyol and a curative are added into the oligomer having the terminal isocyanate group for a polymerization so as to form the modified polyurethane. Based on a total weight of the modified polyurethane being 100 wt %, a content of a hard segment of the modified polyurethane ranges from 15 wt % to 45 wt %.
