A new cyclic monomer

2-oxo-3-methylene-5

6-diphenyl-1

4-dioxan

was synthesized. Thestructure of the intermediates and the monomer were determined by IR

H NMR

C NMR andelemental analysis. This new monomer is different from other cyclic monomers in this series

it isa solid （mp 108--109℃）and not very reactive

but still can undergo free radical ring-openingpolymerization. The free radical polymerization was carried out at 130℃. The structure of theresulting polymer was discussed and charaterized by IR

C NMR and elementalanalysis. The molecular weight of the polymer was estimated by viscosity determination.
