摘要
Carbosilane dendrimers Gn-[(ONNMe2)NiBr2] m, containing up to sixteen terminal pyridylimine nickel complexes, have been studied as catalysts for polymerization of ethylene; the microstructure and the oligomer/polymer distribution are significantly affected by the generation of the dendritic precursor.
