Abstract: This invention relates to a thermoplastic elastomer resin composition for a moisture-permeable waterproof film, including a thermoplastic elastomer resin composed of a hard segment containing polybutylene terephthalate and a soft segment containing polyethylene glycol and polytetramethylene glycol, wherein the polyethylene glycol is contained in an amount of 30 to 70 wt % and the polytetramethylene glycol is contained in an amount of 1 to 10 wt %, based on the total weight of the thermoplastic elastomer resin. A moisture-permeable waterproof film formed of the elastomer composition and a moisture-permeable waterproof fabric configured such that the moisture-permeable waterproof film is stacked on at least one surface of a substrate fiber are also disclosed.

Abstract: Provided is a polyester-based resin composition including: (a) at least one type of dicarboxylic acid component selected from an aromatic dicarboxylic acid and an ester-forming derivative of the aromatic dicarboxylic acid; (b) a bisphenyl fluorene-based diol component; and (c) a tetracyclobutane-based diol component, wherein a content of the bisphenyl fluorene-based diol component is 20 to 90 mol % relative to the total of the diol component and a glass transition temperature (Tg) is greater than or equal to 100° C.
