In this paper we present, for the first time, the NMR investigation of the solution structure of the alkyl cationic titanium compound produced by reaction of 1,3-dimethoxy-p-Bu-1-calix[4]arene titanium dichloride and methylaluminoxane in the required conditions of ethylene polymerization. The role the methylalumoxane plays in the reaction with titanium compound is analyzed by NMR. (C) 2002 Elsevier Science B.V. All rights reserved.
