Two new monomers

4 methylene 2 styryl 1

3 dioxolane and 4 methylene 2 styryl 2 methyl 1

3 dioxolane were synthesized.Their free radical and cationic polymerizations were investigated.The structures of the obtained polymers were characterized based on their IR

1H and 13 C NMR data.The polymerization mechanisms were proposed upon the structures of the polymers obtained.The effects of 2 substituted groups in the 1

3 dioxolane ring on the polymerization and mechanism were discussed...
