The catalytic polymerization of chloroalkyne (e.g. propargyl chloride and 1,4-dichloro-2- butyne) in the presence of the catalyst[e.g. MoCl5 (I),WCl5 (Ⅱ),Mo (CO)6+CBr4+hv system (Ⅲ),Mo (CO)6+CCl4+hv system(Ⅳ), has been studied.It was found that the chloroakyne can be catalyzed for polymerization by the catalyst or systems, and the yield of poly (chlorealkyne) is the best when catalytic system is(CO)5 W=C (OEt) ph+AlCl3 (anhydrous)at-30℃ , polymerzation time is 2h and molar ratio of catalyst to monomer is 0.01:1.The poly (propargyl chloride) and poly-(1,4-dichloro-2-butyne) react with triethylamine to give poly (N-chlorotriethylammoniopropargyl)and poly [1,4-di (N chlorotriethylammonio)-2-butyne]. The IR spectra, molecular weights (Mn), intrinsic viscosity ([n]), electric conductivity σ and thermal analytic data of these polymers were measured. The IR spectra of these polymers shows the bonds at about 1625～1632 cm-1 due t0 C=C conjugated, These polymers are all cunjugated polymers sp2- containing carbon in the main chain. The X ray diffraction of these poly (chloroalkyne) shows that the poly (propargyl chloride) and poly(1,4-dichloro-2-butyne) are amorphous , the poly (N- chlorotriethylammonioniopropargyl) and poly[1,4-di (N-chlorotriethylammonio)-2-butyne] are crystalline.
