Title:

METALLOCENE-CATALYZED OLIGODECENES, THEIR PRODUCTION AND THEIR USE AS COMPONENT IN LUBRICANTS

Document Type and Number:

WIPO Patent Application WO1999067347

Kind Code:

A3

Abstract:

The invention relates to oligodecenes which are obtained by oligomerisation of linear 1-decene, whereby up to 40 mol %, in relation to the quantity of linear 1-decene, of other linear C8-C12-1-alkenes can be included by polymerization, in the presence of a titanium, zirconium or hafnium metallocene catalyst and an activator on a basis of aluminium-organic, boron-organic or carbo-cationic compounds, and which have possibly been hydrogenated following oligomerisation. Said oligodecenes have a number average molecular weight of between 500 and 200,000. The invention further relates to their use as components in lubricants, especially motor oils and transmission oils.
