摘要
Polymer-containing polyether polyamines containing terminal aromatically-bound amino groups are produced by in situ polymerization of a polyether polyamine with an olefinically unsaturated monomer. The polyether polyamine starting material must have terminal aromatic amino groups, a molecular weight of from 800 to 10,000 and an aromatic amino group content of from 0.3 to 16 wt. %. Suitable olefinically unsaturated monomers include alpha , beta -unsaturated nitriles, aromatic vinyl compounds, alpha , beta -unsaturated carboxylic acids and esters thereof, vinyl esters, vinyl halides, vinylidene halides, alpha , beta -unsaturated carboxylic acid amides and aminoalkyl esters of unsaturated carboxylic acids. Acrylonitrile/styrene mixtures are preferred monomers. The starting materials are employed in quantities such that the product modified polyether polyamine contains from 1 to 60 wt. % polymer or graft-polymer. The product polyamines are particularly useful in the production of polyurethanes.
