| abstract |
The invention relates to thermal conversion products comprised of maleic anhydride and oligoalkenes which can be obtained by the oligomerization of linear C8- to C12-1-alkenes, preferably in the presence of a titanium, zirconium or hafnium-metallocene catalyst and in the presence of an activator based on organoaluminum, organoboron or carbocationic compounds. Said conversion products comprise a vinylidene double bond portion of over 30 % and a numerical mean molecular weight ranging from 1,000 to 20,000. The invention also relates to derivatives of the thermal conversion products with amines or alcohols and to the use of said derivatives as fuel and lubricant additives. |
