Abstract: The invention relates to polyvinylamine derivatives containing hydrophilic centres, of the formula I in which R , R , R , 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

Abstract: A process for preparing polyvalent and physiologically degradable carbohydrate receptor blockers by enzymatic glycosylation reactions and the use thereof for preparing carbohydrate building blocks The invention relates to a process for preparing polyvalent polymer-based carbohydrate receptor blockers which cause no intolerance reactions in vivo either in their entirety or in the form of degradation products. The carbohydrate side chain of the receptor blocker is assembled by enzymatic glycosylation reactions in aqueous buffer systems and homogeneous phase directly on the biodegradable polymer; the yields of the glycosylation reaction being considerably improved by comparison with the yields of known processes, as a rule taking place quantitatively and distinctly increasing the loading densities. Furthermore, a process for preparing the free oligosaccharides by means of the carbohydrate receptor blocker is prepared according to the invention is proposed.
