    摘要: Aromatic carbonyl compounds, in particular arylene ether ketones, are prepared by reacting an appropriate reagent system in the presence of free Lewis acid and a complex between a Lewis acid, for example, aluminum trichloride, and an inorganic salt controlling agent, for example, lithium chloride, and, optionally, a diluent, such as methylene chloride. The process is particularly advantageous for the preparation of substantially or all para-linked arylene ether ketones as the presence of the Lewis acid/Lewis base complex markedly reduces alkylation and ensures the substantial absence of ortho substitution.

    摘要: The preparation of poly(arylene ether ketones) by Friedel-Crafts polymerization, in the presence of a Lewis acid catalyst and a diluent, is conducted under conditions in which the polymer and/or its complex with the catalyst is suspended in the diluent during at least part of the polyreaction mixture if desired. The dispersant may be a polymer or an organic compound containing at least eight carbon atoms and is preferably a Lewis base. The dispersant preferably contains at least one molecular segment substantially compatible with the poly(arylene ether ketone) or its complex with the Lewis acid and substantially incompatible with the diluent and at least one molecular segment substantially compatible with the diluent and substantially incompatible with the poly(arylene ether ketone) or its complex with the Lewis acid.

    摘要: A process for producing an aromatic polyketone which comprises polymerizing an appropriate monomer or monomers by a Friedel-Crafts polymerization reaction using a Lewis acid catalyst. A controlling agent such as a Lewis base may be added to the reaction medium and/or the reaction is conducted under specified conditions to control the reaction. The reaction medium comprises, for example, aluminum trichloride as the Lewis acid, an organic Lewis base such as N,N-dimethylformamide or an inorganic Lewis base such as sodium or lithium chloride, and a diluent such as methylene chloride or dichloroethane. The amount of Lewis acid, the amount of Lewis base, the temperature of the reaction and the monomer to diluent molar ratio are varied depending on the monomer system to obtain melt-processable, high molecular weight, substantially linear polymers, for example poly(carbonyl-p-phenylene-oxy-p-phenylene), poly(carbonyl-p-phenylene-oxy-p-phenylene-oxy-p-phenylene), and the like. Copolymers containing up to 30% by weight of an aromatic sulfonyl halide comonomer can also advantageously be produced by this process.
