Abstraet--2-(2',4'-Dichlorophenyl)-4-methylene-l,3-dioxolane was synthesized and polymerized by radical (AIBN and photochemically) and cationic (I 2, BF 3 . OEt2) routes. A polymerization mechanism is proposed based on the analysis of the resulting polymers.
## Abstract The methylene derivatives of 1,3โdioxolane were proved to yield homoโ and binary or ternary copolymers via freeโradical polymerization, depending on initiation type and reaction conditions. While different authors reported experimental data on these compounds, no explanation of such pol
