Abstract
Methyl 2,5-dichlorobenzoate (1) war polymerized in DMF with the NiBr 2 /PPh 3 /Zn catalyst system to produce poly[2-(methorycarbonyl)phenylene-1,4-diyl] (2). Tthe molecular weight distribution of 2 war monomodal and the degree of polymerization war around 100. The hydrolysis of 2 yielded poly(2-carboxyphenylene-1,4-diyl) (3). Polymer 3 was soluble in quinoline and pyridine as well as aqueous sodium hydroxide. The catalytic decarboxylation of 3 produced poly(p-phenylene) (PPP) powder. The electrical conductivity of a pressed pellet was as high as 18 S/cm after vapor phase doping with SbF 5
