P-Phenoxybenzoyl chloride

The electrophilic route for the production of aromatic polyether ketones involves the use of Friedel-Crafts catalysts. AICI3 is used as a catalyst for the polymerization of p-phenoxybenzoyl chloride as such, or p-phenoxy-benzoyl chloride or terephthaloyl chloride and 1,4-diphenoxybenzene to give a PEK. A PEEK is obtained by the use of p-phenoxyphenoxybenzoyl chloride, respectively. The process is carried out at low temperamres, such as 0-30°C. Due to the heterogeneous nature of this reaction, generally undesirable lower molecular weight polymers are produced. 

In Friedel-Crafts reactions, ortho substitution of the polymer is more likely to occur if the reaction is conducted at elevated temperatures and for a relatively long reaction time. To overcome these problems, it has been proposed to use a boron trifluoride catalyst in anhydrous hydrogen fluoride. Another procedure uses lithium chloride and aluminum chloride to polymerize p-phenoxybenzoyl chloride as the ketone monomer and p-phenoxybenzenesulfonyl chloride as the sulfone monomer. ...
