Polymerization of Dioxepane

Polymerization of six-membered cyclic formals has apparently not been reported. Polymeri-ion of 1,3-dioxepane can be initiated by camphor sulfonic acid ° [Pg.185]

5-trioxepane, a product of condensation of trioxane with ethylene oxide, can be polymerized by cationic mechanism both in solution and in bulk [Pg.185]

Polymerizations carried out with boron trifluoride catalyst in dichloroethane solvent result in several reactions that occur simultaneously. A polymer and a copolymer with a different cyclic [Pg.185]

At low temperatures, the amount of dioxolane that forms in the above reaction decreases considerably and can become zero. [Pg.186]

Ring-opening polymerizations of trioxocane leads to the following polymer [Pg.186]
