In its crude form, polyacetylene is black, insoluble, nonprocessible, and unstable. Now, ylide‐nickel catalysts have opened up an approach to the preparation of novel polyacetylenes in a stabilizing polyacrylonitrile matrix. These were characterized by IR and UV spectroscopy. The composition of the polymers can be controlled; the degree of polyene conjugation is dependent on the choice of ligand. Even for polyacetylene contents over 50%, the polymers are soluble and easily processed.
