Patent ID: 7037976

Claim:
A free flowing powder composition with a particle size of less than or equal to 800 μm consisting essentially of: (a) 100 parts by weight of one or more styrenic block copolymers, at least one of which is a block copolymer (a1) comprising: at least one block S having a glass transition temperature Tg above 25° C., which block S contains polymerized units of a vinylaromatic monomer and forms the rigid phase (c1); and at least one elastomeric block B/S having a Tg below 25° C., which elastomeric block B/S contains polymerized units of both a vinylaromatic monomer and a conjugated diene in random sequence and forms the soft phase (c2), wherein the phase volume ratio of block S to block B/S is chosen so that the amount of the rigid phase in the total block copolymer is from 1 to 40% by volume and wherein the amount of the conjugated diene is less than 50% by weight on the whole of the copolymer; and (b) no plasticizing oil.
