CHARACTERISTICS OF POLYMERIZATION OF POLYFLUORINATED OXYGEN-CONTAINING AROMATIC-COMPOUNDS IN PLASMA

The characteristics of the polymerization in plasma of polyfluorinated aromatic compounds containing oxygen in the groups -OCH3, -OCF2H, -OC F3, -OCH2(CF2)2H, and [GRAPHICS] were investigated. It was established that the main structural feature of the polymers produced from oxygen -containing fluoroaromatic compounds in a glow discharge plasma is the significant content of carboxyl groups. The presence of hydrogen atom s in the substituent R for compounds of the ArOR type leads to an incr ease in the polymerization rate if the substituent is short. Just as f or compounds that do not contain oxygen, the reactivity of oxygen-cont aining fluoro-substituted aliphatic compounds in plasma chemical polym erization is lower than that of the analogous aromatic compounds.
