摘要：

Preparation and radical ring‐opening polymerization of the exo‐methylene substituted cyclic ketene acetals, 2,4‐dimethylene‐1,3‐dioxolane (I) and 2,5‐dimethylene‐1,3‐dioxane (II), were carried out. Ketene acetals I and II were prepared by dehydrohalogenation of the corresponding cyclic haloacetal with potassium tert‐butoxide in tetrahydrofuran at –78°C and ambient temperature, respectively. I underwent radical polymerization with essentially quantitative ring‐opening with di‐tert‐butyl peroxide in dimethylformamide at 120°C. On the other hand, II underwent both ring‐opening polymerization and vinyl polymerization under the same conditions of the polymerization of I. The differences of polymerization behavior between I and II were also discussed. Copyright © 1990 John Wiley & Sons, Inc.
