FIELD: chemistry.
SUBSTANCE: invention relates to fluorine-containing acrylic acid esters, in particular to a novel monomer - (perfluoro-2-trichloromethylisopropyl)acrylate, and polymer made therefrom - (perfluoro-2-trichloromethylisopropyl)acrylate, which can be most effectively used for making light-conducting strands and coatings of optical waveguides. Monomer (I) is obtained from hexafluoroacetone and acryloyl chloride. Reaction of hexafluoroacetone with sodium trichloroacetate in dimethyl formamide produces 1,1,1-trichloro-3,3,3-trifluoro-2-(trifluoromethyl)propan-2-ol, acylation of which in presence of triethylamine in a medium of acetonitrile yields desired perfluoro-2-trichloromethylisopropylacrylate with output of 75 %, wherein purity of produced monomer is 99.9 %.
EFFECT: polymer is obtained through radical polymerisation of said monomer in presence of a polymerisation initiator.
