Abstract of the Disclosure Radiation polymerizable polyetherurethane- acrylates having pendent fluorocarbon substituents are disclosed. These novel compositions of matter may be radiation polymerized, e.g., by electron beam, actinic light or heat, to a light transmissive material. The fluorocarbon substituent of the disclosed polyetherurethane- acrylates generally have the formula -W-Rf, wherein W is a divalent connecting moiety and Rf is a highly fluorinated, preferably perfluorinated, aliphatic, aryl or alkaryl radical. These compositions have increased shelf life, may be utilized as 100% solids, and their time and extent of curing may be precisely controlled. These novel radiation curable compositions are particularly useful for speciality application, such as in joining electro-optical components, and as a protective coatng.
