Patent ID: 7560503

Claim:
An oil gel composition comprising 100 parts by weight of a block copolymer composition and about 300 to about 2000 parts by weight of an extending oil, said block copolymer composition comprising: a. from 5 to 70% by weight 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 comprises at least two polymer blocks each substantially made of an aromatic vinyl compound and at least one polymer block substantially made of a conjugated diene compound and having an apparent molecular weight of from 360,000 to 430,000 and; ii) said radial styrenic block copolymer has three or more polymer arms attached to the residue of a cross-linking agent or multifunctional compound, and comprises at least two polymer blocks each substantially made of an aromatic vinyl compound and at least one polymer block substantially made of a conjugated diene compound and wherein the polymer arms have an average apparent molecular weight greater than 125,000 and b. from 95 to 30% by weight of an elastomer (E1) 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 conjugated diene compound.
