Title
Evaluation of catalytic activity in ethylene polymerization and ethylene/10-undecen-1-ol copolymerization of new orthopalladated complexes derived from tridentade ligands [C,N,S]
Abstract

This paper describes catalytic applications of new orthopalladated complex/MAO systems in polymerization of ethylene and copolymerization of ethylene/10-undecen-1-ol. Orthopalladated complexes 1–5 were synthesized from tridentate ligands [C, N, S], with a general formula of PdLX, where L = [Ph2NNC(CH3)CSRSR] and R = CH3, CH2CH2 and X = Cl, CCPh, CCSi(CH3)3. These catalytic systems show high catalytic activity in ethylene polymerization, especially when the reactions were carried out at a temperature of 80 °C. The polyethylene obtained is linear with narrow molecular weight distributions, indicating that Pd/Al systems behave as single site catalysts. The results obtained in copolymerization of ethylene/10-undecen-1-ol indicate that orthopalladated complex/MAO system produces copolymers with molecular weight distributions unimodal and close to 2, indicating that the Pd/Al systems also act as single site catalysts.
