Abstract
Block copolymer containing compositions, to be used in rotational molding, the compositions comprising at least: PA1 (a) 100 parts by weight of a block copolymer containing at least two predominantly poly(monovinyl aromatic) blocks and at least one predominantly poly(conjugated diene) block, the poly(conjugated diene) block preferably being selectively hydrogenated; PA1 (b) from 10 to 80 parts by weight and preferably from 20 to 50 parts by weights, of a linear low density poly(ethylene) or copolymers of predominantly ethylene and minor amounts of other .alpha.-olefin comonomers; and PA1 (c) from 20 to 100 parts by weight and preferably from 20 to 45 parts by weight of a plasticizer.
