Hydrophilic groups containing poly(vinylamine) derivatives, process for their manufacture and use thereof as pharmaceutical compounds, substrates for active substances and foodstuff ingredients

摘要

The invention relates to polyvinylamine derivatives containing hydrophilic centres, of the formula I in which R<1>, R<2>, R<3>, X, w, x, y and z are as defined, and to a process for their preparation, and to the use of these compounds as medicaments (drugs, pharmaceuticals), active compound (active ingredient) carriers and as foodstuff auxiliaries. The preparation starts, in particular, from highly pure polyvinylamines containing the recurring unit of the formula Ia whose preparation is likewise described.a
