Gamma radiation, polysiloxane

Gamma radiation from a °Co source has also been used (77,114,132-135) as an effective technique for crosslinking polysiloxanes. In a comparative study of gamma radiation with peroxides, Schomburg et al. (77) noted that each approach immobilized polysiloxanes, but that the formation of polar decomposition products is avoided with radiation. Radiation offers the additional advantages of the crosslinking reaction occurring at room temperature, and columns can be tested both before and after immobilization of the stationary phase.
