摘要：

Structural differences in the polymers obtained by catalysed cure of the ethynylaryl-terminated monomer [1,4-(1,3-HC=CC6H4CH2O)C6H4]2CMe2 (1) could not be detected by IR or NMR spectroscopy. However, a study of the solvent-free catalysed polymerization of the model monomer, phenylacetylene, showed that the extent of cyclotrimerization decreased in the order (eta-CP)CO(CO)2 much greater than (eta-Cp)2Ni almost-equal-to (PPh3)2NiCl2 much greater than (PPh3)2PdCl2 with an accompanying increase in the degree of linear polyene formation, suggesting that this is so also for the catalysed cure of 1.
