【Abstract】 The catalytic polymerization of alkyne in the presence of [(CO) 5MoC(O)R]·N(CH 3) 4+Et 3OBF 4+AlCl 3 (R=phenyl, thiophenyl and furanyl groups) systems has been studied. It was found that phenylacetylene, proparagyl chloride, diphenylacetylene and 1,4 dichloro 2 butyne can be catalyzed for the polymerization and propargyl alcohol and 1,4 butynediol cannot be catalytically polymerized by these systems. Effects of polymerization conditions on the yield of polymers were also investigated. IR spectra, number average molecular weight ( Mn ), the intrinsic viscosity (η) and electric conductivity (σ) of these polymers were measured. The X ray diffraction of these polymers show that these polymers are amorphous.更多还原
