This dissertation deals with the cyclopolymerization of dipropargyl derivatives containing functional groups such as ester, carboxylic acid and amine. In the polymerization of these dipropargyl derivatives, $MoCl_5$ was more effective catalyst than $WCl_6$, especially $WCl_6$ gave no polymer in the polymerization of dipropargyl malonic acid. n-$Bu_4Sn$ exhibited good cocatalytic activity in the polymerization of dipropargyl malonic acid derivatives. On the other hand, $EtAlCl_2$ was very effective cocatalyst in the polymerization of dipropargyl phenylamine by $WCl_6$. The spectral datas and solubility behavior of the resulting cyclopolymers supported that these polymers possesses polyene structure having cyclic recurring unit in the polymer backbone. The cyclopolymers prepared in this study were mainly amorphous. The electrical conductivities of $I_2$-doped polymers were in the range of $10^{-3}-10^{-1}$ Scm$^{-1}$. The poly(diethyl dipropargylmalonate) have high molecular weight(Mn: 127100) and good film forming property.
