Abstract

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//center dot/(organo-Li, organo-Mg or polysilane). 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. 1 tab.

Method for the preparation of 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/.(organo-Li, organo-Mg or polysilane). 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.
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.

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.
