Model for the effects of water on the cationic UV-curing of cyclohexyl epoxides

Polyol has a similar effect on the curing reaction as water (Figures 3-6). The polyol functions as a proton donor for both initiation and proton transfer. In addition, the primary hydroxyl groups at the end of long flexible chains enhanced the reactivity of either the AM or ACE. The polyol also prov...

Summary:Polyol has a similar effect on the curing reaction as water (Figures 3-6). The polyol functions as a proton donor for both initiation and proton transfer. In addition, the primary hydroxyl groups at the end of long flexible chains enhanced the reactivity of either the AM or ACE. The polyol also provided a better medium than water for crossover from chain to step growth and transfer to chain growth again.
