Insights into CO/styrene copolymerization by using PdII catalysts containing modular pyridine-imidazoline ligands

The performance of the cationic [Pd(Me)2-nCln- (N-N’)] complexes as catalyst precursors in CO/4-tert-butylstyrene copolymerization under mild pressures and temperatures was analyzed in terms of the productivity and degree of stereoregularity of the polyketones obtained.
