摘要：
The interactions of substituted poly(N-phenylmaleimides) with low- and high-molecular-weight amines were studied. Colourless chloroform solutions of polymers, which carry electron-attracting substituents in benzene rings, turn intensively red on addition of amines in neutral or basic media depending on the nucleophilicity and accessibility of amino groups. Absorption spectra of the solutions in the visible range suggest that the formation of colour complexes consists in an interaction of free electron pairs of amines with adjacent carbonyl groups of the polyimides.
