PURPOSE:To obtain a polymer compsn. excellent in heat resistance, solvent resistance, moldability, etc., by compounding a polyester polymer with a specific modified block copolymer in a specified wt. ratio. CONSTITUTION:This polymer compsn. is prepd. by compounding, in a specified wt. ratio. a polyester polymer with a modified OH-terminated block copolymer which has at least either a polymer block mainly comprising arom. vinyl compd. units or a hydrogenated polybutadiene block formed by hydrogenating a polybutadiene block having a 1,2-bond content of 20% or lower and at least one polymer block selected from the group consisting of a hydrogenated polyisoprene block, a hydrogenated polybutadiene block formed by hydrogenating a polybutadiene block having a 1,2-bond content of 30-70%, and a hydrogenated isoprene-butadiene random copolymer block and/or a modified OH-terminated block copolymer which has at least one polymer block mainly comprising arom. vinyl compd. units and at least one polyisobutylene block. |
