New catalysts for the alternating copolymerization of 4-tert-butylstyrene/CO
摘要:
New cationic palladium(II) complexes, containing C-S-nitrogen chelate ligands with pyrazol moieties, catalyze the copolymerization of styrene with CO under mild conditions, to produce a syndiotactic copolymer. Molecular weight and polydispersity for the obtained polymers are among the best reported for bisnitrogen planar ligands. (C) 2001 Elsevier Science B.V. All rights reserved.
