Abstract
Abstract Electrically conductive polymer blends of an acetylene polymer, such as poly(acetylene), and a triblock thermoplastic elastomer, such as styrene-butadiene-styrene, are disclosed. In addition, a method for preparing such blends wherein the acetylene polymer is preferentially formed in the central elastomeric block of the triblock copolymer is disclosed. These blends exhibit high conductivity and elasticity upon doping with electron donors or electron acceptors.
