In article the results of experimental studies and modeling of physic-chemical param-eters of plasma of DC current discharges with electrolyte cathode are analyzed at the pres-sure range of (1.01-0.101)·105 Pa for molecular and atomic gases. The data on physical pa-rameters of plasma (electric field strength, cathode voltage drop, gas temperatures) are giv-en. The results of measurements and calculations of active species concentrations, electrons, as well as molecule distributions on vibrational levels and electron energy distribution func-tions are analyzed.

Key words: plasma, gas discharge, physical parameters, active species, process mechanisms

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.
