Abstract: Graft polymers such as grafted polyacetylene and devices based on derivatives of these polymers are produced utilizing a specific process. The process includes the steps of polymerizing a monomer such as acetylene in the presence of a host polymer such as polyisoprene to produce a graft polymer.

For example, when the graft polymerization is performed in the presence of a solvent for an appropriate host polymer, the entire graft polymer is solvated. The solvated graft polymer is then employable to produce films of polymers on a substrate which are in turn useful in structures such as devices.
