Abstract

LLDPE with narrow polydispersity was produced from ethylene by orthogonal tandem catalysis using a mixture of cis-P,P′-dibromo{5,17-dibromo-11,23-bis(diphenylphosphino)-25,26,27,28-tetrapropoxycalix[4]arene}nickel (1) and ZrCl2Cp2 (3) in the presence of methylaluminoxane; the polymer produced has only ethyl branches as ramification.
