Abstract

The present invention relates to at least simply unsaturated polyolefins with a number mean molecular weight in the range of 400 to 1,500 dalton and a dispersibility of M.sub.W /M.sub.N <1.2, obtained through catalytic dimerization from at least simply unsaturated olefin-oligomers, as well as to the method for their production. The present invention further relates to derivatives of these polyolefins which can be obtained by functionalizing at least a double link of the polyolefin. The invention also relates to the use of polyolefins and/or functionalization products as additives for fuels or lubricants.
