Abstract
A solution process for the preparation of high molecular weight polymers of alpha-olefins selected from the group consist-ing of homopolymers of ethylene and copolymers of ethylene and C3-C12 higher alpha-olefins, by polymerization of ethylene and/or mixtures of ethylene and C3-C12 higher alpha-olefins in the presence of a catalytic amount of a titanium-containing coordination catalyst in an inert solvent at a temperature in excess of 105 °C is disclosed. The improvement is characterized in that: (a) the catalyst is activated with a solution of alkoxyalkyl aluminum in inert solvent; and (b) the process is operated at least in part at a temperature of at least 180 °C. In an embodiment, the coordination catalyst is formed from a first com-ponent and a second component, the first component containing titanium and second component being selected from the group consisting of alkoxy aluminum alkyl and mixtures of alkyl aluminum and alkoxyalkyl aluminum. The aluminum al-kyl is of the formula AR n X3-n and the alkoxy alkyl aluminum is of the formula AR' m OR"3-m, in which each of R, R' and R"
may be the same or different and is alkyl or aryl of 1-20 carbon atoms, X is halogen, n is 1-3 and m is 0-2.
