Description

Methyl Vinyl Ketone (MVK) is a colorless, irritating and reactive liquid.<br>Photo-polymerization of MVK was reported by H. W. Milville et al and Y. Tabata et al.<br>Now, we have investigated the photo-polymerization kinetics of MVK which carried out in liquid phase by the light of longer wavelength than 300n.m..<br>The photo-polymerizations with azobisisobutyronitrile (AIBN) and without initiator have been studied in various solvents such as ethyl acetate, dioxane and acetone.<br>This reaction was considered to proceed by free radical mechanism from the fact that the polymerization is retared by radical scavenger.<br>The overall rates of polymerzation (Rp) were expressed as follows:<br>Rp=k[MVK]2.2 in dioxane Rp=k[MVK]3.8 in acetone Rp=k[AIBN]0.6[MVK]1.6 in dioxane Rp=k[AIBN]0.6[MVK]2.2 in acetone<br>This results did not agree with usual first order reaction on monomer.<br>Also, the apparent activation energies were measured to be 3-6kcal/mole.<br>Good results were obtained on application of MVK to graphic arts for photo-polymerizable compositions.
