Notes:
Radical copolymerizations of α-trimethylsilyloxystyrene (TMSST), a silyl enol ether of acetophenone, with electron-accepting monomers such as maleic anhydride (MA) and fumaronitrile (FN) were investigated. TMSST underwent alternating copolymerizations with both MA and FN irrespective of the feed composition, whereas it failed to copolymerize with diethyl fumarate (DEF). The alternating copolymers of TMSST with MA and FN were desilylated with concentrated hydrochloric acid as a catalyst to form polymers containing γ-lactone rings. The formation of the lactone rings was also observed in the desilylation of an alternating copolymer of TMSST with acrylonitrile (AN) under the similar conditions.
