Polymeric polydonor complexons and method for preparation thereof

摘要

Polymeric polydonor complexons having more than six sites in a structural unit are described. The complexons are of the formulae: (a) and (b) wherein P is a linear or three-dimensional polymeric skeleton, x is oxygen or an group wherein R is hydrogen, an alkyl group of 1-6 carbon atoms, a phenyl group or a substituted phenyl group. The described complexons are obtained by reaction of a polymeric compound of the formula P -XH wherein P and X are as defined above with a dianhydride of the corresponding complexon in the presence of a tertiary amine and, optionally, an inert solvent.
