J. Umezawa et al., RING-OPENING POLYMERIZATION OF 3,3,3-TRIFLUORO-1,2-EPOXYPROPANE - STUDIES ON MONOMER REACTIVITY AND POLYMER STRUCTURE, Polymer Journal, 26(6), 1994, pp. 715-721
The polymerization reaction of 3,3,3-trifluoro-1,2-epoxypropane (TFEP)
with Et2Zn-H2O or potassium hydroxide was investigated. The ring-clea
vage reaction of TFEP occurs only at the beta(CH2-O)-position to give
regioregular, head-to-tail poly(TFEP). The C-13 NMR and F-19 NMR spect
ra of the polymer give information on the dyad tacticity of the polyme
r main chain. It is suggested that the organozinc compound is a stereo
specific catalyst and potassium hydroxide is a non-stereospecific one
for the polymerization of TFEP.
