Four studies are reported: living cyclopolymerization of diethyl dipropargylmalonate by Mo(CH-t-Bu)(NAr)[OCMe(CF{sub 3}){sub 2}]{sub 2} in dimethoxyethane, effect of chain length on conductivity of polyacetylene, nonlinear optical analysis of a series of triblock copolymers containing model polyenes, and synthesis of bifunctional hexafluoro-t-butoxide Mo species and their use as initiators in ROMP reactions.
