Abstract

Esters are used with catalysts (for polymsn of olefins) containing a V salt and a compound of the formula RMgX, LiAIR4 or RaA1Xb, (where R is a 1-12C hydrocarbon group, X is halogen, a = 1-3, b = 0-2 and a + b = 3). The molar ratio V compound:organometallic compound: nitrate or nitrile is 1 : 5 : 0.1-1 : 200 : 200. The primary catalyst is more active, retains its activity for a longer time or can be re-activated, by the use of the nitrate or nitrile ester.
