POLYESTER ELASTOMER RESIN COMPOSITION AND MOULDED ARTICLE FORMED USING SAME

摘要

[Problem] To provide a polyester elastomer resin composition having excellent transparency which comprises 0.1 to 5 parts by mass of an alkali metal salt of organic carboxylic acid having 3 to 40 carbon atoms (B) and 0.3 to 5 parts by mass of a polyfunctional glycidyl group-containing styrene-based polymer (C) with respect to 100 parts by mass of a polyester elastomer (A), wherein the polyester elastomer (A) is a polyether ester block copolymer (A) comprising as main structural components an aromatic dicarboxylic acid component, a C2-6 alkylene glycol component and a polyoxyalkylene glycol component. A moulded article obtained from the composition exhibits excellent transparency and in which problems such as blooming or bleeding of a transparentizing agent to the surface of a moulded article are improved.
