Poly(4-diphenylphosphinostyrene) (1), poly(4-dicyclohexylphosphinostyrene) (2), and poly<1-(4-diphenylphosphinophenyl)ethyliminomethylene> (3) were obtained by polymerization of the corresponding monomers.The polymers were treated with (RhClL2)2 and with (RhClL')2, where L and L' are ethene and 1,5-cyclooctadiene, respectively.These complexes were added stepwise and during this process the 31P NMR spectra were observed. 31P chemical shifts and 103Rh-31P coupling constants were compared with those of monomeric analogues which were treated in the same way.
