NEW SILICONE HAVING LEAVING GROUP

摘要

PROBLEM TO BE SOLVED: To obtain a new specific fluorine-containing silicone having a leaving group, capable of forming a soft strong coating film composition together with another monomer, etc., useful for bridging, coating, etc., in a polymer and capable of chemically modifying a surface of a material. ;SOLUTION: A new fluorine-containing silicone expressed by the formula [Q is a (substituted) divalent hydrocarbon; R₁ to R₆ are each a hydrocarbon optionally having a fluorine atom or a leaving group; at least one of R₁ to R₃ and at least one of R₄ to R₆ are leaving groups, and further a molecule has at least one fluorine atom]. Together with another monomer, etc., the silicone can form a soft strong coating film composition and enables easy chemical modification, on and of the surface of various materials such as powder or fiber. Also, it can control the physical properties of the material and is useful for bridging, coating, etc., in a polymer. The compound is obtained by adding 1,8diiodo-3,3,4,4,5,5,6,6-octafluorooctane to tetramethoxysilane, magnesium and tetrahydrofuran under refluxing to react them.;COPYRIGHT: (C)1997,JPO
