The polymerization of 1-methoxy -1-ethynylcyclohexane (MEC) was carried out by various transition metal catalysts. The catalysts MoC15, MoCli, and WCIC gave a relatively low yield of polymer (< 16%). The catalytic activity of Me-based chloride catalyst was greater than that of W-based chloride catal

## A novel highly conjugated polymer with two cyclic recurring units per monomeric unit was prepared from tripropargylamine using various transition metal catalysts. WC&, PtCl,, and RuCl, were found to be effective catalysts, whereas the tungsten-based and molybdenum-based catalysts gave a low yie
N-Carbazolylacetylene (CzA) was polymerized in the presence of various transition metal catalysts including WCl 6 , MoCl 5 , [Rh(NBD)Cl] 2 , and Fe(acac) 3 to give polymers in good yields. The polymers produced with W catalysts were dark purple solids and soluble in organic solvents such as toluene
