Patent ID: 7001956

Claim:
An article comprising at least one hydrogenated 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, said hydrogenated block copolymer composition comprising: a. a tetra-branched block copolymer (IV) having a number average molecular weight of 100,000 to 800,000 represented by the general formula (A-B) 4 X; b. a tri-branched block copolymer (III) having a number average molecular weight of from 75,000 to 600,000 represented by the general formula (A-B) 3 X; c. a di-branched block copolymer (II) having a number average molecular weight of from 50,000 to 400,000 represented by the general formula (A-B) 2 X; and d. a linear diblock copolymer (I) having a number average molecular weight of from 25,000 to 200,000 represented by the general formula A-B; where: i. A represents a polymer block of a mono alkenyl arene; ii. B represents a polymer block of a hydrogenated conjugated diene; iii. X represents the residue of an alkoxy silane coupling agent having the formula R x —Si—(OR′) y , where x is 0 or 1, x+y=4, and R and R′ are the same or different, R is selected from aryl hydrocarbon radicals, linear alkyl hydrocarbon radicals and branched alkyl hydrocarbon radicals, and R′ is selected from linear and branched alkyl hydrocarbon radicals; and iv. the relative amounts of copolymers IV, III, II and I are from 0 to 5 weight percent IV, from 0 to 60 weight percent III, from 40 to 95 weight percent II and from 2 to 10 weight percent I, where the total of I, II, III and IV equals 100 weight percent.
