Abstract:
The present invention discloses silicone oils which are structured with a copolymer comprising a large percentage of alkane groups. Using high percentage pendant alkane helps provide silicone with ideal gel properties (G′>G″, particularly >1000 cP, more preferably 2000-30,000 cP) and viscosity, after fracture, of 10 to 1000 cP, preferably 30-500 cP MW of polymer and exact chain length are selected to ensure that, when forming gel upon cooling after mixing polymer and silicone, the polymer viscosity will not be so high upon crystal formation that gel cannot form, yet also will not be so low that polymer will phase separate.
