SYNTHESIS AND PROPERTIES OF 1,1,2-TRIFLUO RO-1,3-BUTADIENE COPOLYMERS

Emulsion copolymerization of 1,1,2-trifluoro-1,3-butadiene with chloro prene, isoprene, and butyl acrylate was studied. Sol-gel analysis of t he prepared copolymers and homopolymer was performed. The intrinsic vi scosities of the sol fractions of the copolymers were determined, and the equivalent molecular mass of the gel fractions of the copolymers w ere calculated. The parameters of phase and relaxation transitions and thermal stability of homo- and copolymers were investigated. It was s hown that isoprene-1,1,2-trifluoro-1,3-butadiene copolymer exhibits th e properties of an elastomer and is thermally stable at temperatures u p to 280 degrees C.
