Other metathesis routes to polyacetylenes

The direct metathesis polymerization of acetylenes is not the only route to polyacetylenes using olefin metathesis chemistry. Below are summarized some of the other methods that have been developed in recent years. 

For further information on polyacetylenes, particularly their physical properties, see the reviews of Masuda (1987d, 1994b) and Breslow (1993).
