Molar mass distribution of vinylidene fluoride-3-oxaperfluorohex-1-ene copolymers☆

Abstract The effect of polymerization temperature and pressure on M distribution of vinylidene fluoride-3-oxaperfluorohex-1-ene copolymers was studied. It was shown that M distribution curves of samples synthesized at 60 and 95° and a pressure of 24 atm are bimodal. M distribution of samples obtained at pressures of 1 and 7 atm was found to be unimodal, however, the curves are complex. It was established by minimum intensity of light scattering that the form of micro-emulsion of 3-oxaperfluorohex-1-ene varies with pressure in the system examined.
