| Abstract: | 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. |
