Claims5
A thermoplastic copolymer having inherent electroconductive properties comprising a copolymer of equimolar amounts of a tetrathiafulvalene monomer having the formula:
- ##STR8## in which R.sup.1 is selected from the group consisting of hydrogen, CH.sub.2 .dbd.CH--, and CH.sub.2 .dbd.CH--CH.sub.2 --, R.sup.2 is selected from the group consisting of CH.sub.2 .dbd.CH--, and CH.sub.2 .dbd.CH--CH.sub.2 --, and a polycyano-quinodimethane monomer having the formula:
- ##STR9## in which R is selected from the group consisting of CH.ident.C--, CH.sub.2 .dbd.CH--, and CH.sub.2 .dbd.CH--CH.sub.2 --, R.sup.1 is R or H, and R.sup.2 is NC-- or H.
A thermoplastic copolymer having inherent electroconductive properties comprising a copolymer of equimolar amounts of a tetrathiafulvalene monomer having the formula:
- ##STR10## in which R is selected from the group consisting of hydrogen, CH.sub.2 .dbd.CH--, and CH.sub.2 .dbd.CH--CH.sub.2 --, R.sup.2 is selected from the group consisting of CH.sub.2 .dbd.CH--, and CH.sub.2 .dbd.CH--CH.sub.2 --, and a dicyanoquinondiimine monomer having the formula:
- ##STR11## in which R is selected from the group consisting of CH.sub.2 .dbd.CH--, and CH.sub.2 .dbd.CH--CH.sub.2.
