Title:
POLYURETHANE ELASTOMER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2005/116102
Kind Code:
A1
Abstract:
Disclosed is a method for producing a thermoplastic polyurethane elastomer having excellent heat resistance and mechanical characteristics. This method enables to obtain a thermoplastic polyurethane elastomer having a low hardness without using a plasticizer. Specifically disclosed is a method for producing a polyurethane elastomer by reacting a polyol compound and a polyisocyanate compound which is characterized in that a polyester ether polyol (A), which is obtained through ring-opening polymerization of a mixture of an alkylene oxide and a lactone monomer by an initiator, is used as the whole or a part of the polyol compound.
