OIL-CONTAINING GELS FORMED FROM BLOCK COPOLYMERS WITH CONTROLLED LINK DISTRIBUTION AND ESTER OILS Russian patent published in 2010 - IPC C08L53/02 C08K5/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a composition of an oil-containing gel, which contains a block copolymer with controlled link distribution and at least one non-aromatic ester oil. The block copolymer is formed from monoalkenyl and a conjugated diene. The block copolymer undergoes selective hydrogenation and contains block A from monoalkenylarene homopolymer and block B with controlled link distribution in form of a medial block formed from monoalkenylarene and a conjugated diene. The non-aromatic ester oil is natural oil, eicosyl erucate or C_12-15 alkyloctanoate. Oil content is equal to 250-2000 pts. wt per 100 pts. wt of the hydrogenated block copolymer.

EFFECT: invention enables to obtain stable transparent gels with improved properties.
