摘要：
DATA ARE PRESENTED WHICH DEMONSTRATE THAT 2-METHYLENE-1,3-DIOXEPANE 6 POLYMERIZES WITH A QUANTITATIVE RING OPENING TO FORM POLY- ″EPSILON″ -CAPROLACTONE VIA A FREE RADICAL MECHANISM. ON THE OTHER HAND, 2-METHYLENE-1,3-DIOXOLANE (ETHYLENE KETENE ACETAL) 4 AND 2-METHYLENE-1,3-DIOXANE 5, UNDER THE SAME CONDITIONS, GENERATED POLYMERS WITH MIXED RING-OPENED AND NONRING-OPENED STRUCTURES. IN COPOLYMERIZATION MONOMER 6 ALSO SHOWED A HIGH TENDENCY TOWARD RING OPENING BY WHICH THE ESTER FUNCTIONALITY COULD BE CONVENIENTLY INTRODUCED INTO THE BACKBONE OF THE ADDITION POLYMERS.
