POLYARYLENEETHERKETONES OBTAINING WITH REACTION OF NUCLEOPHILIC SUBSTITUTION

The article deals with the study of influence of the synthesis conditions on the molecu-lar weight of polyaryleneetherketones (PAEK), received with nucleophilic substitution reac-tion of activated aryl halide. The synthesis of PAEK with the nucleophilic substitution reaction carried out as partially hydrolyzed homopolycondensation of phenolates and aromatic dihal-ides containing a carbonyl group in the molecule and derivatives of polycondensation of ar-omatic bisphenols with activated aromatic dihalides, and aromatic nitro compounds. The nu-cleophilic substitution of halogen in aryldihalogens proceeds through formation of Meisen-heimer complex, where the negative charge of the electron-electron ring stabilizes the group.
