    摘要： A coating formulation for application to surfaces associated with combustion, such as fuel injectors, and surfaces subjected to elevated temperatures, such as fuel supply components, to prevent the deposition at high temperatures of carbon or graphite on such surfaces, such as stainless steel and alloyed steel compositions. The coating formulation forms a thin layer of polymer coating on the surface by chemical grafting involving the use of a graft initiator to create active bonding sites, on the metal surface, for the silicone-based prepolymer to undergo polymerization on the metal surface. The bonding and polymerization are completed in a single application process without using complex equipment. The coating and process helps surfaces associated with combustion and surfaces subjected to elevated temperature reduce carbon or coke formation at temperatures up to 700° F. and thereby improves the durability and performance of those surfaces.

    摘要： The present invention provides new fluoromonomers having the generic structure: CF2═CF(OCH2CH2)nOR where n is an integer and R is a functional group and methods for producing same. A new method of synthesizing the fluoromonomers is provided. The present invention also relates to new fluoropolymers prepared from any one or combination of the new fluoromonomers and having the generic structure: —[—CF2CF{(OCH2CH2)nOR}—]m— where n is an integer, m is an integer and R represents an unsubstituted or inertly substituted hydrocarbyl group. The method also relates to new copolymers or terpolymers prepared from the new fluoromonomers alone, the new fluoromonomers and existing fluoromonomers or the new fluoromonomers and existing hydrocarbon or functionalized hydrocarbon monomers.
