Title
(EN) Process to make aminated polyolefins
Abstract
(EN)

The invention relates to a process to make aminated polyolefins involving the steps of:

ozonolysis of one or more low-molecular weight polyolefins with at least one end group that is unsaturated, in the presence of an alkanol-hydrocarbon mixture, to form polyolefin-alkoxyhydroperoxides,

catalytic reduction of the polyolefin-alkoxyhydroperoxides with hydrogen and a suitable catalyst, to form a mixture of hemiacetals and hemiketals, in the presence of a solvent,

removal of the catalyst and optional washing of the mixture resulting from step 2, to remove undesired side products,

reductive amination of the hemiacetal hemiketal mixture to form the aminated polyolefin end product, preferably at a temperature of 50-200° C., optionally in the presence of a solvent, and

removal of the catalyst and optional removal of the solvent. The aminated products obtained are pre-eminently suited for use as an adjuvant in oils and fuels.
