| Abstract: | A blending polyether type polyurethane elastomer was prepared by blending polyoxypropylene ether glycol with polyterahydrofuran ether glycol. The effects of reacting temperatures and the structure of polyether on the degree of reaction, ripening time on the viscosity of polyurethane solution and the blending ratio of the two kinds of polyesters on the physical-mechanical properties of polyurethane were investigated. The results show the reactivity of the polyoxypropylene ether endcapped with oxirane to be close to that of polyterahydrofuran ether glycol. |
