copolymerized polyether polyamide resin

摘要

An object of the present invention is to provide a copolymerized polyether polyamide resin for coating on or for impregnation to a woven or knitted fabric, which resin further enhances slippage resistance and tear strength affecting the developing property of an airbag which is one of the automobile safety parts, as compared with those in the prior art. According to the present invention, a copolymerized polyether polyamide resin for coating on or for impregnation to a woven or knitted fabric is provided, characterized in that , elongation and elastic modulus of the copolymerized polyether polyamide resin are not less than 1000% and not more than 15 MPa, respectively. The copolymerized polyether polyamide resin has a constitution wherein said copolymerized polyether polyamide resin is such that wherein a soft segment comprising a polyether polyamide constituted from a polyether diamine compound and a dicarboxylic acid compound is bonded to a hard segment comprising a polyamide constituted from an aminocarboxylic acid compound and/or a lactam compound.
