Patent Number Title Of Patent Date Issued
4232142 Production of polyarylene ether sulphones and ketones November 4, 1980
Aromatic polymers containing benzenoid groups and oxygen atoms in the polymer chains are made by the action of an alkali metal hydroxide on a dihalogenobenzenoid compound in which each halogen atom is activated by an inert electron-attracting group such as --SO.sub.2 --. When a bis-(
