The poly(BTFPA) produced by the W(CO)6-based catalyst at 30 °C was soluble in p-(CF3)2C6H4, and had relatively high molecular weight ([η]=0.352 dL/g in p-(CF3)2C6H4). The main chain of the polymer was composed of alternating double bonds, and the polymer was a dark brown solid. The temperature at which the weight loss of the polymer started was higher than 300 °C. The polymerization behavior and polymer properties for BTFPA are compared with those for phenylacetylene and [o-(trifluoromethyl)phenyl]acetylene.
