Patent ID: 7166672

Claim:
An oil gel composition comprising 100 parts by weight of at least one hydrogenated block copolymer composition and about 1000 to about 2000 parts by weight of an extending oil, said hydrogenated block copolymer comprising: a. 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; b. 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; c. 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; and d. 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 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, 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 I, II, III and IV are from 2 to 10 weight percent I , from 40 to 95 weight percent II, from 0 to 60 weight percent III, from 0 to 5 weight percent IV, and where the total of I, II, III and IV equals 100 weight percent.
