Abstract
The present invention is directed to a heterogeneous gas phase polymerization process to produce true polyacetylene (PA; C2H2) in powder form, and the resultant PA product. The present invention is additionally directed to a chlorinated polyacetylene (CPA) compound comprised of primarily CHCl units and CH double bond units. The CPA compound can be comprised of at least 67.3 wt % Cl, and have a weight average molecular weight (Mw) as measured by GPC of greater than 30,000 and contain less than 1.0 mol % carbon-carbon branching. The CPA compound according to the invention can exhibit a glass transition temperature (Tg) of at least about 185° C. to about 270° C.
