Abstract
Abstract A polymer composition comprising: (A) 15 to 40% by weight of a hydrogenated product of a block copolymer comprising a vinyl aromatic compound (a 1 ) and a conjugated diene compound (a 2 ), (B) 4 to 30% by weight of an isopropenyltoluene polymer comprising meta-iso-propenyltoluene as the main constituting unit, and (C) 40 to 80% by weight of a compound selected from the group consisting of α-olefin polymers (c 1 ) having a number average molecular weight ranging from 250 to 5000 and squalane (c 2 ), wherein the total amount of the components (A), (B) and (C) is 100% by weight.
