Abstract 4-(Iminomethyl)phenol and 4-(iminomethyl)benzoic acid terminated aliphatic polyetherswere obtained by conversion of Jeffamines with respective aromatic aldehydes. Mixtures of these polymerswith polyamidines showed improved compatibility or even complete miscibility because of ionic complexesformed between the end groups of the modified polyethers and the basic amidine groups. Depending oncomposition and molecular weight of the components, blends with two or one glass transitions wereobtained. In the case of 4-(iminomethyl)phenol terminated polyethers, deprotonation of the end groupsresulted in a distinct change of the UV/vis absorption spectrum. This spectral alteration is discussedwith respect to quantification of interactions in polymer blends.
