摘要

正

A new cyclic monomer

2-methyl-2-methocycarbonyl-5-methylene 1

3-dioxlan-4-one

wassynthesized successfully. The monomer and intermediate were characterized by

H NMR

C NMR

INEPT （Intensive Nuclei Enhanced by Polarization Transfer） technique

IR andelemental analysis. Anionic polymerization of the monomer was carried out in anhydrous THF at.70℃

and 9-fluorenyllithium was used as initiator. The polymer strucure was determined byIR

NMR and elemental analysis. Molecular weight of the polymer was estimated by viscositymeasurement in DMSO at 30℃.
