Patent ID: 7048979

Claim:
An injection molded, dipped, rotational molded, slush molded, fiber spun, blow molded, extruded or over molded article comprising a block copolymer composition and at least one other component selected from the group consisting of olefin polymers, styrene polymers, tackifying resins, polymer extending oils, and engineering thermoplastic resins, wherein said block copolymer composition comprises: a. from 20 to 50% by weight, based on the total weight of the block copolymer composition, of a first block copolymer selected from linear styrenic block copolymers (SBC1), radial styrenic block copolymers (SBC2) and mixtures thereof, wherein: i. said linear block copolymer is of the formulae: (A-B) 2 X wherein A represents a polystyrene block; B represents a polymer block of a conjugated diene, n is an integer greater than or equal to 1, and X is the residue of a coupling agent or multifunctional monomer and has an apparent molecular weight greater than 250,000 and; ii. said radial styrenic block copolymer is of the formulae: ((AB) n ) m X wherein A represents a polystyrene block; B represents a polymer block of a conjugated diene, n is an integer greater than or equal to 1, m is an integer greater than 2, and X is the residue of a coupling agent or multifunctional monomer each of said polymer arms has an average apparent molecular weight greater than 125,000 and b. from 80 to 50% by weight based on the total weight of the block copolymer composition, of an elastomer (El) having an apparent molecular weight of 120,000 to 250,000, comprising a styrenic diblock copolymer having one polymer block substantially made of an aromatic vinyl compound and one polymer block substantially made of a conjugated diene compound.
