摘要：
Cationic palladium(II) complexes of the type [L2Pd(CH3)(CH3CN)]BF4 (L-2 =1,3-bis(diphenylphosphino)propane (Dppp) or 1,2-bis( 2,5-dimethylphospholano)benzene (Me-Duphos)) were found to catalyze the alternating copolymerization of ethene, propene and cyclopentene with sulfur dioxide, as well as the terpolymerization of ethene, propene and sulfur dioxide. The resultant materials are high melting solids with an alternating alkene-SO2 structure and an exclusive head-to-tail enchainment for propene. (C) 1998 Elsevier Science S.A.
