| abstract | A cyclic ether or cyclic acetal is polymerized in the presence of a catalytic amount of a salt containing the hexafluoroantimonate (hfa) ion. Specified cyclic compounds are trioxan, tetroxan, 1-3-dioxolan, tetrahydrofuran, 3-3-bis-(chloromethyl) oxacyclobutane, styrene oxide, propylene oxide, 1-3-5-trioxepan, 1-3-dioxepan and ethylene oxide. These cyclic compounds may be copolymerized with each other or with up to 50% preferably up to 20% of styrene or styrene derivatives, aldehydes, allyl compounds, cyclic esters, unsaturated aliphatic hydrocarbons, vinyl esters and ethers and N-vinyl an C-vinyl heterocylic compounds, lists being given. Specified hfa catalysts include carbonium hfas such as triphenylmethyl-, diphenylmethyl- and tritolmethyl-, carboxonium hfas such as dioxolinium, acetyl and benzoyl hfa, oxonium and hydroxonium hfas, e.g. triethyloxonium hfa, aryl diazonium hfas, iodonium hfa and substituted iodonium hfas and nitrosyl and nitryl hfas. The polymerization takes place, preferably under anhydrous conditions, by bulk solution or suspension, e.g. in hydrocarbons such as cyclohexane. Examples are given of the polymerization of trioxan, 1-3-dioxolane, tetrahydrofuran, of tetrahydrofuran with styrene, of trioxan with styrene, with vinyl acetate, with beta-propiolactone, with butyraldehyde, with 2-vinyl-1-3-dioxan, with 4-phenyl-1-3-dioxan, with piperonal or with allyl acetate, of 3-3-bis(chloromethyl) oxacyclobutane with or without styrene, of dioxolan with trioxan, with indene or with isoprene, of 1-3-dioxepan, 1,3,5-trioxepan and of styrene oxide. The products may be acetylated. |
