Abstract
A method of forming a conductive polymer comprising a blend of at least one processable polymer, polyacetylene and a dopant by impregnating the processable polymer with a Ziegler-Natta catalyst; exposing the impregnated polymer to acetylene gas, whereby substantially linear molecules of polyacetylene are formed within a matrix of the processable polymer; and introducing a dopant into the polyacetylene, whereby a conductive blend is formed.

A method of forming a conductive polymer comprising a blend of at least one processable polymer, polyacetylene and a dopant, the method comprising:
- (a) impregnating at least one processable polymer with a Ziegler-Natta catalyst;
- (b) exposing said impregnated polymer to acetylene gas, whereby substantially linear molecules of polyacetylene are formed within a matrix of the processable polymer;
- and
- (c) introducing a dopant into the polyacetylene, whereby a conductive blend is formed.
A method of forming a conductive polymer blend comprising polyethylene and iodine-doped polyacetylene, the method comprising:
- (a) impregnating polyethylene with a Ziegler-Natta catalyst of the formula Ti(n-OBu).sub.4 /Et.sub.3 Al;
- (b) exposing said impregnated polyethylene to acetylene gas, whereby polyacetylene is formed within a matrix of polyethylene;
- and
- (c) introducing iodine into the polyacetylene, whereby a conductive polymer is formed.
