Abstract
1,054,205. Polymerizing cyclic ethers or cyclic acetals. BRITISH INDUSTRIAL PLASTICS Ltd. Nov. 23, 1965 [Nov. 23, 1964], No. 47553/64. Headings C3P and C3R. A cyclic ether or cyclic acetal is polymerized in the presence of a catalytic amount of a carbonium hexafluoroarsenate. The cyclic compound may be copolymerized with a comonomer in amounts such that the comonomer makes up between 0À01 and 50% of the units of the resulting copolymer. Specified cyclic compounds are trioxane, tetroxan, 1,3-dioxolan, tetrahydrofuran, 3,3-bis(chloromethyl)oxacyclobutane, styrene oxide, 1-35-trioxepan, 1-3- dioxepan and ethylene oxide. The comonomers may be one of the above cyclic compounds, styrene, styrene derivatives, aldehydes, alkyl compounds, cyclic esters, unsaturated aliphatic hydrocarbons, vinyl ethers and esters and N- vinyl and C-vinyl heterocyclic compounds. Lists are given. It is preferred that these comonomers are present in amounts between 0À1 and 20% of the polymer. The preferred carbonium compound is triphenyl methyl hexafluoroarsenate while the diphenylmethyl, the diphenyltolylmethyl, the phenylditolylmethyl, the trioctylmethyl, and the dioxolinium, the acetyl and the benzoyl derivatives are listed. The polymerization may take place under anhydrous conditions, by bulk or liquid polymerization, at 0‹ to 100‹ C. in an inert atmosphere. The catalyst may be removed from the polymer by washing or neutralizing especially with ammonia or an amine. The polymers may have added thereto stabilizers, anti-oxidants, pigments, U.V.-absorbers and may be stabilized by chemically reacting the end groups, e.g. acetylating with acetic acid or anhydride.
