METHOD FOR PRODUCTION OF (CO)POLYMERS OF 1,1,2-TRIFLUOROBUTADIENE-1,3

摘要

FIELD: production of polymers. SUBSTANCE: copolymers of 1,1,2-trifluorobutadiene with other monomers are prepared by aqueous-emulsion polymerization at 1-20 C and pH 3.5-7 in the presence of emulsifier and initiator. Complexes of alkyl cobalt (III) with tridentant ligands are used as said initiator, its quantity being 0.04-0.3 mass parts per 100 mass parts of monomers. Alkyl1{2- [(2-aminoethyl)imino]-3-alkyl2-pent-3-en-4-olate}(1,2-ethane diamine)- cobalt (III) halides where alkyl 1 represents C₁-C₁₆alkyl, alkyl 2 represents H₁C₂H₅, H-C₇H₁₅, halide is iodine or bromine are used as aforementioned ligands. EFFECT: improves efficiency of the method.
