Controlled functional density poly (secondary amines) and method for preparation thereof |
摘要 |
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 (b1) 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.
