Abstract
The polymerization reaction of 3,3,3-trifluoro-1,2-epoxypropane (TFEP) with Et2Zn-H2O or potassium hydroxide was investigated. The ring-cleavage reaction of TFEP occurs only at the β(CH2–O)-position to give regioregular, head-to-tail poly(TFEP). The 13C NMR and 19F NMR spectra of the polymer give information on the dyad tacticity of the polymer main chain. It is suggested that the organozinc compound is a stereospecific catalyst and potassium hydroxide is a non-stereospecific one for the polymerization of TFEP.
