Methyl Vinyl Ketone Polymerization

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.
