摘要：PURPOSE: To obtain the subject composition containing a specific block copoly mer, a vinylaromatic hydrocarbon-based polymer, filler and wax, excellent in slipperiness, blocking resistance at high temperatures and firm-forming prop erty and useful for heat-shrinkable film suitable for heat-shrinkable label, etc. CONSTITUTION: This composition contains (A) 20-100 pts.wt. block copolymer of a vinylaromatic hydrocarbon (M1 ) with a conjugated diene (M2 ) having (59/50) to (90/10) weight ratio, (B) 0-80 pts.wt. vinylaromatic hydrocarbon-based polymer comprising a polymer of M1 , a copolymer of M1 with (meth)acrylic acid (ester) (M3 ) having >=(5/95) weight ratio of M1 to M3 or a rubber-modified styrene-based polymer, (C) an inorganic filler and (D) PE wax or amide-based wax, wherein when the total amount of components A and B are 100 pts.wt., the contents of the components C and D are each 1-5 pts.wt. and 0.05-15 pts.wt.
