Abstract

An electrically conductive block copolymer of polyisoprene and polyacetylene and a method of making the same are disclosed. The polymer is prepared by first polymerizing isoprene with n-butyllithium in a toluene solution to form an active isoprenyllithium polymer. The active polymer is reacted with an equimolar amount of titanium butoxide and subsequently exposed to gaseous acetylene. A block copolymer of polyisoprene and polyacetylene is formed. The copolymer is soluble in common solvents and may be doped with I/sub 2/ to give it an electrical conductivity in the metallic regime.

Resonance Raman excitation profiles of polyacetylene/polyisoprene block co-polymers in toluene

Conference Agnew, S.F.; Aldissi, M.

We have measured the resonance Raman spectra and excitation profiles of a soluble polyacetylene/polyisoprene block-copolymer in toluene solution. These are the first reported excitation profiles that have been referenced to an internal solvent standard, the toluene Raman bands. We find that this copolymer exhibits the same two bands in the C=C stretch region, i.e., 1463 and 1519 cm/sup /minus/1/, that have been attributed to a bimodal distribution in conjugation length for polyacetylene thin films. The 1519 cm/sup /minus/1/ peak has been associated with short chain segments of polyacetylene and we assign it to an average chain length of N=11 C=C'smore »« less

Soluble silylated polyacetylene derivatives and their use as percursors to novel polyacetylene-type polymers

Patent Ziegler, J.M.

This patent describes a soluble polymer or copolymer having -C(R)=C(R)/sub 4/- as a majority of repeating structural units and a molecular weight M/sub eta/ {ge} about 10,000. The polymer or copolymer being the product of the polymerization of acetylenic monomers at a temperature within the range of -10{sup 0} to 150{sup 0}C in an inert atmosphere and in the presence of a tungsten (III or IV) compound and a cocatalyst selected from the group consisting of organolithium compounds, organomagnesium compounds, polysilanes, and compounds containing a Si-Si, P-P, S-S, Ge-Ge, As-As, Sn-Sn, Sb-Sb, or Te-Te bond.

Soluble silylated polyacetylene derivatives, their preparation and their use as precursors to novel polyacetylene-type polymers

Patent Zeigler, J.M.

Polymerization of acetylenic monomers is achieved by using a catalyst which is the reaction product of a tungsten compound and a reducing agent effective to reduce W(VI) to W(III and/or IV), e.g., WCl/sub 6/ x (organo-Li, organo-Mg or polysilanes). The resultant silylated polymers are of heretofore unachievable, high molecular weight and can be used as precursors to a wide variety of new acetylenic polymers by application of substitution reactions. They can be used as electrodes in batteries.
