Anionic polymerization of vinyl ketones

open access: diamondDie Makromolekulare Chemie, 1963
AbstractStereoregular polymerizations of some vinyl ketones were examined by using several anionic catalysts.Methyl vinyl ketone was found to be polymerized by some catalysts such as calcium zinc tetraethyl and phenylmagnesium bromide (etherate) to give highly crystalline polymers which melt at about 160°C.
