THERMOPLASTIC POLYESTER ELASTOMER LAMINATE EXCELLENT IN WEATHERABILITY

摘要

PROBLEM TO BE SOLVED: To provide an elastomer laminate which is excellent in weatherability and low temperature flexibility, high in moisture permeability, and low in water absorbency and can be used outdoors or in a place irradiated with light.;SOLUTION: In the laminate, a polyester elastomer film is laminated on a substrate of a fibrous substance. The laminate is an aromatic dicarboxylic acid component and a polyether glycol component in which a short chain glycol component and at least two alkylene oxide units are repeated randomly as polymer constituents, contains 70-95 wt.% of the random copolymerization polyether glycol component in which the content of an alkylene oxide unit having quaternary carbon in the total weight is below 10 wt.%, comprises a polyester elastomer containing an ultraviolet absorbent. and has water absorption of 0.005-20 wt.% and moisture permeability (measured at thickness of 30 μm) of 3,000 g/m³ day or above.;COPYRIGHT: (C)2004,JPO&NCIPI
