摘要：

The arylpropargyl-ether-terminated monomer (1,4-HC=CCH2OC6H4)2CMe2 was polymerized to just before the gel point in the presence of various catalysts. Changes in the H-1 n.m.r. spectra show that (a) (eta-Cp)Co(CO)2 gives rise exclusively to acetylene cyclotrimerization, (b) (eta-Cp)2Ni and (PPh3)2NiCl2 each result in both cyclotrimerization and non-aromatic polyene formation, and (c) (PPh3)3RhCl gives branched eneyne dimers.
