<p>The present invention is a radiation sensitizer or crosslinking agent having the formula wherein n is from 2 to 6; R1 is selected from H and methyl radicals; R2 is a diradical selected from the group consisting of alkylene, cycloalkylene, aralkylene, and arylene diradicals having from 1 to 16 carbon atoms; and X is a polyfunctional radical wherein the functional groups are selected from -O-, , (where R is H or a (C1-C4) alkyl radical) and mixtures thereof, the radical having from 2 to 6 functional groups. The radiation sensitizer is useful in fluoropolymer compositions. The present invention also includes a method comprising the step of irradiating a fluoropolymer composition. The composition can be melt processed followed by irradiation. The radiation sensitizer of the above composition is particularly stable during melt processing. Melt processing can include melt blending, such as extruder blending, and melt forming, such as wire coating.</p> |
