The living ylide–mediated polymerization of methyl methacrylate was successfully achieved at room temperature with quantitative initiator efficiency using (1-naphthyl)triphenylphosphonium triphenylmethanide initiator. A low temperature (-30 oC) and 1 hr reaction time for the preparation of the ylide by reaction of (1-naphthyl)triphenylphosphonium bromide and triphenylmethyl potassium were shown to be essential. The resulting ylide gives a nearly quantitative initiator efficiency and is capable of operating at temperatures well above ambient temperatures.
