Abstract:
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 in order to form the aminated polyolefin end product, optionally in the presence of a solvent, and removal of the catalyst and optional removal of the solvent.
