METHOD OF SYNTHESIS OF TRIFLUOROCHLOROETHYLENE COPOLYMERS Russian patent published in 1997 - IPC

Abstract RU 2088600 C1

FIELD: chemical technology, polymers. SUBSTANCE: copolymers of trifluorochloroethylene, alkylvinyl ether and hydroxyalkylvinyl ether were synthesized by copolymerization of the indicated monomers in medium of organic solvent in the presence of radical initiating agent - azocompound and neutralizing agent - ethanolamine of the general formula: (R1)(R2)N - CH2CH2OH where: R1 and R2 - H, -CH3, -C2H5, -CH2CH2OH taken at amount 1-7% of monomers mass. Synthesis is carried out at 55-60 C. At process termination the residual vinyl monomers were distilled off under vacuum. Synthesized copolymers were used for protection of building structures and technological equipment. EFFECT: improved method of synthesis. 2 tbl
