Abstract

A class of substituted urethane acrylates and methacrylates having an aliphatic backbone is provided, the members of the class having at least one ether or polyether group with at least one pendent fluorinated organic group attached thereto. The novel compositions may be radiation polymerized, e.g., by electron beam, actinic light or heat, to a light transmissive material which is well suited to optical application, such as coupling optical fibers and light emitting diodes so as to transmit light therebetween.
