PURPOSE: To provide a molding material having good rupture resistance against stress and low moist permeability and easy for deep drawing molding by making the material contain a styrene-contg. polymer, a polyolefin, and a mixture consisting of not less than two different block copolymers.
CONSTITUTION: This thermoplastic molding material comprises 1-89 wt.% polymer contg. styrene (A), 1-89 wt.% polyolefin (B), and 1-20 wt.% mixture of at least two different block copolymers manufactured by anion polymn. of styrene, and butadiene or isoprene (C). At least one of these block copolymers is a start-shaped block copolymer contg. 50-90 wt.% styrene, and at lest one of the other block copolymer is a start-shaped block copolymer contg. 10-50 wt.% styrene, or a linear block copolymer of styrene and butadiene having at least three S-Bu-S blocks.
