The invention relates to a process to make aminated polyolefins involving the steps of: ozonolysis of one or more low-molecular weight polyolefin 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 DEG 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.
(ZH) 本发明涉及一种胺化聚烯烃的制备方法，包括如下步骤：在链烷醇-烃混合物存在下，含有至少一个不饱和端基的一种或多种低分子量聚烯烃进行臭氧分解，以形成聚烯烃-烷氧基氢过氧化物；在溶剂存在下，采用氢气和合适的催化剂对聚烯烃-烷氧基氢过氧化物进行催化还原，以形成半缩醛和半缩酮的混合物；脱除催化剂和任选地洗涤步骤2获得的混合物，以除去不希望的副产物；优选在50-200℃温度下，任选地在溶剂存在下，半缩醛半缩酮混合物进行还原胺化以形成胺化聚烯烃最终产物；和脱除催化剂和任选地脱除溶剂。获得的胺化产物优异地适于作为油和燃料中的助剂。
