摘要：
Crosslinking of the ethynylaryl-terminated monomer (1,4-(1,3-HC = CC6H4CH2O)C6H4)2CMe2 is catalysed by (eta-Cp)Co(CO)2, (eta-Cp)2Ni, (PPh3)2MCl2 (M = Ni, Pd) and (PPh3)3RhCl as shown by a reduction in differential scanning calorimetry peak exotherm temperature. In some cases two separate exotherm peaks are observed corresponding to catalysed and uncatalysed reactions. Nickelocene, for which this is a novel application as a catalyst, is particularly active.
