| titleOfInvention | Production of aromatic polyketones |
| abstract | A process for the production of a thermoplastic aromatic polyketone which process comprises reacting in the presence of a fluoroalkane sulphonic acid, preferably CF 3 SO 2 OH, the reactants selected from the following class: n (a) at least one aromatic monocarboxylic acid of the formula: ##STR1## where --Y-- is a direct link, --O--, --S--, --NAr'-- where Ar' is a monovalent aromatic radical (preferably phenyl); Ar is a divalent aromatic radical but must not be --Ph--CO--Ph-- or --Ph--SO 2 --Ph-- (where --Ph-- is phenylene) when y is 1; and n is an integer of ≧1 and y is an integer of 1 to 3; n (b) a mixture of at least one aromatic dicarboxylic acid of the formula: ##STR2## where --X-- and --X'-- are independently a direct link --O--, --S--, --NAr'-- where Ar' is as defined in (a); m is 0 or an integer of ≧1; and Ar is as defined in (a); and at least one aromatic compound of formula: ##STR3## where --Z-- is --O-- or a direct link; and Ar, n, and y are as defined in (a); and n (c) a combination of (a) and (b). n The aromatic carboxylic acid is particular 4-(4-phenoxy)phenoxy benzoic acid which yield an aromatic polyketherketone having repeat units of the formula ##STR4## |
