Methyl vinyl ketone polymerization.

Polymerization of methyl vinyl ketone with benzoyl peroxide was carried out using the method reported by sorenson and campbell9. Weian zhang shaohua wang xiaohui li jiayin yuan shaolei wang. Poly phenyl vinyl ketone obtained did not exhibit much higher crystallinity. Fires involving methyl vinyl ketone may be extinguished with dry chemical co2 halon water spray alcohol or standard foam water spray or fog solid streams of water may be ineffective.

Methyl vinyl ketone is incompatible with strong oxidizers and strong bases. This polymerization may cause violent ruptures in containers. An enone is a type of an α β unsaturated carbonyl that consists of an alkene conjugated to a ketone. It is soluble in water and polar organic solvents.

Since methyl vinyl ketone fires may produce toxic fumes when tank cars and trucks are involved isolate the area for 1 2 mile in all directions. Sec analysis of the polymerization of a methyl acrylate ctas 2 and 6 mixed b styrene ctas 2 and 6 c dimethyl acrylamide ctas 2 and 5 d maa ctas 1 and 2 e methyl vinyl ketone ctas 2 and 6 and f vinyl acetate ctas 4 and 7 illustrating the variation in dispersity as two ctas are mixed in different ratios. This article describes the copolymerization of methyl vinyl ketone mvk methyl acrylate ma and methyl methacrylate mma with styrene st as reference monomer at 3 4 mpa and 335 k with toluene as solvent. It polymerizes spontaneously upon exposure to heat or sunlight.

Spectra with a varian t 60a using tms as a standard. Phenyl vinyl ketone and methyl isopropenyl ketone were also polymerized by the same organometallic catalysts. The polymerization of isopropenyl methyl ketone and some properties of its polymers paper presented at the 132nd meeting of the american chemical society september 1957 new york. The simplest enone is methyl vinyl ketone butenone ch 2 chcoch 3 enones are typically produced using an aldol condensation or knoevenagel condensation some commercially significant enones produced by condensations of acetone are mesityl oxide dimer of acetone and phorone and isophorone.
