Abstract
The living polymerization of ethylphenylketene (EPK) by a samarium enolate is described. Poly(EPK) with controlled molecular weight and low polydisper sity was obtained in a quantitative yield by the polymerization with the sa marium enolate and polar additives. A wide variety of polar additives inclu ding amides and ureas were shown to facilitate the formation of well-define d poly(EPK).
