Abstract
Synthesis and characterization of polycarbynes, a new class of carbon-based random network polymers. The network backbones of the polymers are composed of tetrahedrally hybridized carbon atoms, each bearing one substituent and linked via three carbon-carbon single bonds into a three-dimensional continuous random network backbone. Silicon, germanium, tin, lead, Group 13 through Group 16 elements, lanthanides, and Group 4 metals can be incorporated into the polymer backbone. The atomic-level carbon network backbone confers unusual properties on the polymers, including thermal decomposition to form diamond or diamond-like carbon.
Claims5
A polymer of the Formula (I):
- [CR].sub.n (I)
- wherein said polymer comprises tetrahedrally hybridized carbon atoms linked to each other by three carbon-carbon single bonds into a three-dimensional continuous random network backbone, and one R linked to each of said carbon atoms, wherein R is the same or different and selected from the group consisting of H, a saturated linear or branched-chain hydrocarbon containing from 1 to 30 carbon atoms, an unsaturated ring hydrocarbon containing 5 to 14 carbon atoms in the ring, each in unsubstituted or substituted form;
- wherein the substituent groups are at least one of halogen, nitro, cyano, alkoxy, carboxy, aryl, hydroxy, heterocyclic alkyl, or heterocyclic aryl groups;
- a halogen, a Group 4 metal, and a Group 13 through Group 16 element, and n is at least 8.
