AbstractHomogeneous polymerization of p-diethynylbenzene (p-DEB) with (pi -C5H5)(PPh3)Ni(C drop CC6H4C drop CH) catalyst has been investigated in terms of added compound, reaction atmosphere, catalyst and monomer concentration and polymerization temperature. The single-component and environmentally stable nickellocene acetylide is an effective catalyst for the p-DEB polymerization, and the polymerization can proceed under mild conditions to give soluble and stable polymers in high yields. The polymerization rate equation can be expressed as R-p = k(p)[M][cat](14), where k(p) = 0.58 1(1.4) mol(-1.4) min(-1) (40 degreesC). The overall polymerization activation energy was found to be 84 kJ mol(-1). Poly(p-diethynylbenzene) so obtained possesses weight average molecular weights as high as 55 700 and an extended pi -conjugated polyene chain structure with pendent groups of p-C6H4C drop CH.
