Butenone is the organic compound with the formula ch 3 c o ch ch 2 it is a reactive compound classified as an enone in fact the simplest example thereof it is a colorless flammable highly toxic liquid with a pungent odor. Methyl vinyl ketone mvk iupac name.

Controlled nitroxide mediated radical polymerization of methyl and phenyl vinyl ketone. Polymer films prepared with a 2 1 ratio of ag ions to polymer acetophenone groups responded with a quench of photoluminescence. Incorporation of silver tetrafluoroborate agbf 4 into poly vinyl phenyl ketone pvpk renders the photoluminescent polymer responsive to ethylene. Controlled nitroxide mediated radical polymerization of methyl and phenyl vinyl ketone.

Vinyl ketone polymers including phenyl vinyl ketone pvk are an important class of polymers due to their ability to degrade upon irradiation with ultraviolet light which makes them useful for a variety of applications. It is soluble in water and polar organic solvents. To prepare well defined diblock copolymer having both a poly phenyl vinyl ketone block and a polystyrene block which type of living radical polymerization technique should be used.

Poly phenyl vinyl ketone obtained did not exhibit much higher crystallinity compared with the conventional polymer whereas some specimens of poly methyl isopropenyl ketone prepared by the at complexes or diethylzinc as catalyst were highly crystalline. Phenyl vinyl ketone and methyl isopropenyl ketone were also polymerized by the same organometallic catalysts. Well defined photodegradable poly vinyl ketone s with predictable molecular weights and low polydispersities pdi 1 16 1 21 were synthesized by raft homopolymerizations of vinyl ketone monomers using s 1 dodecyl s α α dimethyl α acetic acid trithiocarbonate as the raft agent and aibn as the initiator at 70 75 c in 2 butanone or 1 4 dioxane.
