## Abstract New bicyclic 2‐methylene‐1,3‐dioxepanes, were synthesized starting from 2‐bromomethyl‐5,6‐dihydroxy‐1,3‐dioxepanes. The structure of the 2‐methylene‐1,3‐dioxepanes was confirmed by elemental analysis, IR, ^1^H NMR and ^13^C NMR spectroscopy. Radical polymerization of 2‐methylene‐1,3‐dio
Poly (1,3-dioxepane) [PDOP] triol was prepared by cationic ring-opening polymerization with [C 2 H 5 C(CH 2 OCH 2 CH 2 CO ϩ ClO 4 Ϫ ) 3 ], trioxocarbenium perchlorate, as an initiator. The structures of the PDOP triols obtained were verified by 1 H-NMR, FTIR, and GPC results. Initiation, propagation
## Abstract The cationic polymerization of 1,3‐dioxepane (DOP) initiated with trifluoromethanesulfonic acid (I) in the presence of ethylene glycol (EG) was investigated. At sufficiently low concentration of the initiator ([I] > 0.01 mol/L vs. [EG] < 0.20 mol/L), the molecular weights of the obtaine
