MOLDED ARTICLE PRODUCED FROM THERMOPLASTIC POLYMER COMPOSITION AND HAVING EXCELLENT ELEXIBILITY

摘要

PROBLEM TO BE SOLVED: To provide a molded article having excellent flexibility and elastic recovery (low permanent set) and made of a specific thermoplastic polymer composition having excellent shape-retention at a high temperature and melt- molding properties such as extrusion moldability. SOLUTION: The molded article is produced by the thermal molding of a thermoplastic polymer composition composed of (I) a thermoplastic resin produced by the polymerization of monomers consisting of a methacrylic acid ester and other monomer as an arbitrary component and (II) rubbery crosslinked particles obtained by the copolymerization of a monomer mixture containing an acrylic acid ester and a polyfunctional monomer and satisfying the following conditions. (1) The weight ratio of I/II is 40/60 to 10/90, (2) the number-average molecular weight of (I) is <=30,000, (3) the average particle diameter of (II) is <=130 nm and (4) at least the component (II) takes a continuous phase.
