摘要：
The present invention relates to a polyester polyurethane material with long term hydrolysis resistance which is prepared from perchlorates and a polyester polyol comprising structure unit I, II, and III. The polyester polyurethane material having a mole ratio of structure unit II to III of 1:1.5 to 1.5:1 has better long term hydrolysis resistance. In another aspect of the present invention, there is provided soles, carpets, rollers, sealing strips, coating, tires, wipers, steering wheels or gaskets prepared from the polyester polyurethane material, and a use of the polyester polyurethane material.
