WCL‐catalyzed bulk copolymerization of phenyl‐acetylene (PhA) with 3‐bromo‐1‐propyne was carried out. Soluble, colored products with different comonomer content were obtained. The copolymer structure was estimated by IR spectroscopy and elemental analysis; their molecular weight being 2000–3000. These copolymers were used to study the ability of doping with such acceptors as FeCL3, Sn(Ph) 4 , tetracyanobenzoquinone (TCNQ). The conductivity of the copolymers was found to increase from 10 −13 to 10 −3 /cm with doping. Substitution of the lithium derivative of the polymer with SnCL 3 for Li leads to an increase of conductivity as well.
