Article Description

A novel type of chelating block copolymer, polystyrene-block-poly-m-vinyltriphenylphosphine (PS-b-PPH), was reacted with (CHCN)PdCl or (PPh)PdCl, and the products were examined with FTIR, P NMR spectroscopy, and elemental analysis. The complexation of triphenylphosphine groups of these polymers with palladium compounds induces micellization in the system, and no polymer gels were formed. The morphology of the Pd-containing diblock copolymer micelles was studied with transmission electron microscopy (TEM). The size and kind of micellar aggregates depends strongly on the molecular weight of diblock copolymer, its composition, and metal compound type. Block copolymer-stabilized Pd nanoparticles were prepared by reduction of Pd-containing PS-b-PPH with NH·HO, LiB(CH)H, and LiAlH and analyzed by TEM, X-ray photoelectron spectroscopy, and wideangle X-ray scattering techniques. It is found that the morphology of nanoparticles is controlled by the way of reduction and by the nature of the polymeric aggregates.
