Phenyl vinyl ketone polymerization.

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. 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. Phenyl vinyl ketone and methyl isopropenyl ketone were also polymerized by the same organometallic catalysts. In this study a series of photocleavable well defined triblock copolymers with the photocleavable middle block of poly phenyl vinyl ketone ppvk were readily synthesized by raft polymerization.

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. It is soluble in water and polar organic solvents. Controlled nitroxide mediated radical polymerization of methyl and phenyl vinyl ketone. Controlled nitroxide mediated radical polymerization of methyl and phenyl vinyl ketone.

Write out the general chemical equation for the polymer synthesis. 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.
