A composition which is curable to an elastomer comprising: A polymer or mixture of polymers of the formula <CHEM> wherein: X are monovalent moieties having ethylenic unsaturation which can be the same or different; Y are divalent linking groups which can be the same or different; m is an integer of 0 to 1; D are monovalent moieties which can be the same or different selected from the group consisting of hydrogen, an alkyl group of 1 to about 10 carbon atoms, aryl, and substituted aryl; R are divalent hydrocarbon groups which can be the same or different; R<1> are monovalent moieties which can be the same or different selected from the group consisting of alkyl, substituted alkyl, aryl, and substituted aryl; R<2> are monovalent moieties which can be the same or different selected from the group consisting of alkyl, substituted alkyl, aryl, and substituted aryl; R<3> are monovalent moieties which can be the same or different selected from the group consisting of alkyl, substituted alkyl, vinyl, aryl, and substituted aryl; R<4> are monovalent moieties which can be the same or different selected from the group consisting of alkyl, substituted alkyl, vinyl, aryl, and substituted aryl; and n is an integer of about 270 to about 1000. A composition which is curable to a pressure sensitive adhesive comprising the above polymer and a sufficient amount of tackifier. The invention also relates to fluorosilane compounds useful in the preparation of silicone macromonomer, their preparation and the preparation of silicone macromonomer. |
