Abstract
Dehydrochlorinated poly(vinylidene chloride) proved to be a conjugated polyeneβpolyene polymer. Shock compression of the polymer formed a large portion of graphite and trace amounts of diamond and of an unknown carbon. The unknown carbon belongs to the hexagonal crystal system and possesses the cell dimension Ξ±~0~ = 0.338 nm. A comparison with known carbynes was made in terms of the crystalline parameters.
