    • A process for preparing a controlled functional density poly(secondary amine) comprising: (a) contacting a polymer containing olefinic unsaturation with carbon monoxide in hydrogen under hydroformylation conditions in the presence of a hydroformylation catalyst to produce a controlled functional density polyaldehyde containing reactive carbon-carbon double bonds, and (b) contacting the polyaldehyde with hydrogen and a primary amine under reductive amination conditions in the presence of a ruthenium-containing imine hydrogenation catalyst or (b.sup.1) contacting the polyaldehyde with a sterically hindered aliphatic or cycloaliphatic primary amine or an aromatic primary amine under reductive amination conditions in the presence of an alkali metal borohydride to produce poly(secondary amine) having a substantially equivalent ratio of secondary amine groups to reactive carbon-carbon double bonds as the ratio of aldehyde groups to reactive carbon-carbon double bonds in the polyaldehyde.
    • 一种制备受控功能密度聚(仲胺)的方法,包括:(a)在加氢甲酰化条件下,在加氢甲酰化催化剂存在下,使含有烯属不饱和的聚合物与一氧化碳在氢气中接触,以产生受控的功能密度聚醛, 碳双键,和(b)在还原胺化条件下,在含钌亚胺氢化催化剂存在下使聚醛与伯胺接触,或(b1)使多醛与空间位阻的脂族或脂环族伯胺或 芳族伯胺在还原胺化条件下在碱金属硼氢化物存在下反应生成具有基本上当量的仲胺基与反应性碳 - 碳双键的比例的聚(仲胺)作为醛基与反应性碳 - 碳双重比例 多醛中的键。
