Claims
- 1. A process for preparing a carbon disulfide homopolymer or carbon diselenide homopolymer, which comprises homopolymerizing carbon disulfide monomer or carbon diselenide monomer, dissolved in a solvent, in the presence of an anionic polymerization catalyst.
- 2. A process according to claim 1, wherein the homopolymerization is carried out at a pressure of up to 10 atmospheres.
- 3. A process according to claim 1, wherein the homopolymerization is carried out at a temperature in the range of -100.degree. to 50.degree. C.
- 4. A process according to claim 1, wherein the polymerization is carried out at a temperature of up to 200.degree. C. under an elevated pressure of up to 10 atm.
- 5. A process according to claim 1, wherein the solvent is a polar solvent.
- 6. A process according to claim 5, wherein the homopolymer is soluble in the solvent.
- 7. A process according to claim 1, wherein the solvent is a non-polar solvent.
- 8. A process according to claim 1, wherein the anionic catalyst is at least one compound selected from the group consisting of alkali metals, alkaline earth metals, alkali metal alkoxides, alkylalkali metals and alkylalkaline earth metals.
- 9. A process acording to claim 8, wherein the anionic polymerization catalyst is sodium, lithium or potassium.
- 10. A process according to claim 1, wherein the concentration of the anionic polymerization catalyst in the solvent is in the range of 0.001 to 3.0 mol/l.
- 11. A process according to claim 1, wherein the reaction is carried out under stirring.
- 12. A process according to claim 1, wherein the homopolymer has a conductivity of about 10.sup.-8 mho/cm.
- 13. A carbon disulfide or carbon diselenide homopolymer obtained by the anionic polymerization of carbon disulfide or carbon diselenide monomer in an organic solvent.
