摘要

正

A new cyclic monomer

2-methyl-2-methoxycarbonyl-5-methylene-1

3-dioxolan-4-one

was synthesized successfully. The monomer and intermediate were characterized by

H NMR

CNMR

INEPT（Intensive Nuclei Enhanced by Polarization Transfer） technique

IR and elementalanalysis. Anionic polymerization of the monomer was carried out in anhydrous THF at -70℃

and 9-fluorenyllithium was used as initiator. The polymer structure was determined by IR

NMRand elemental analysis. Molecular weight of the polymer was estimated by viscosity measurementin DMSO at 30℃.
