Claims
- 1. A process for preparing a thermally stable solid phthalocyanine polymer consisting essentially of the steps of
- (a) combining a dicyano aromatic monoamine and an organic dianhydride to produce an amic-acid linked bisphthalonitrile compound;
- (b) dehydrocyclizing said amic acid linked bisphthalonitrile compound to produce an imide-linked bisphthalonitrile compound; and
- (c) polymerizing said imide-linked bisphthalonitrile compound to produce the desired thermally stable solid phthalocyanine polymer.
- 2. A process for preparing a thermally stable solid phthalocyanine polymer consisting essentially of the steps of:
- (a) combining a dicyano aromatic monoamine and an organic dianhydride to produce an amic-acid linked bisphthalonitrile compound;
- (b) dehydrocyclizing said amic acid linked bisphthalonitrile compound to produce an imide-linked bisphthalonitrile compound; and
- (c) polymerizing by heating said imide-linked bisphthalonitrile compound to produce the thermally stable solid phthalocyanine polymer.
- 3. The process of claim 2 wherein in step (c) said imide-linked bisphthalonitrile compound is heated in contact with metal powder.
- 4. The process of claim 2 wherein in step (c) said imide-linked bisphthalonitrile compound is heated in contact with metal salt.
- 5. The process of claim 4 wherein said metal salt is cuprous chloride.
- 6. A thermally stable solid phthalocyanine polymer formed by the thermal polymerization of an imide-linked bisphthalonitrile compound having the formula: ##STR8## wherein R is a preformed tetravalent organic group with the proviso that said tetravelent organic group contain no additional imide group, and each R" is a trivalent hydrocarbon group.
- 7. The phthalocyanine polymer of claim 6 wherein each R" is a benzene ring.
- 8. The phthalocyanine polymer of claim 6 wherein R is a benzene ring.
- 9. The phthalocyanine polymer of claim 8 wherein each R" is a benzene ring.
- 10. The phthalocyanine polymer of claim 6 wherein R is a ##STR9## group in which R' is an aliphatic or aromatic group.
- 11. The phthalocyanine polymer of claim 10 wherein each R" is a benzene ring.
- 12. The phthalocyanine polymer of claim 11 wherein R' is a 2 to 6 carbon alkylene.
- 13. The phthalocyanine polymer of claim 11 wherein R' is a benzene ring.
- 14. The phthalocyanine polymer of claim 6 wherein R is a ##STR10## group.
- 15. The phthalocyanine polymer of claim 14 wherein each R" is a benzene ring.
