A novel biodegradable, water-resistant polymer material which can be produced with defined material properties is suggested, in particular in the form of foils, films, strips, masses, molded articles or the like, this material consisting essentially of a product of the cross-linking reaction of polysaccharides and/or polypeptides, the hydroxyl, amino, imino, thiol and/or carboxyl groups of which are derivatized at least partially in a non-radical reaction with agents which include groups cross-linkable in a process step following the derivatization and separate therefrom.
Nouveau polymère biodégradable, résistant à l'eau, pouvant être fabriqué avec des propriétés matérielles déterminées, notamment sous forme de feuilles, de pellicules, de bandes, de blocs, d'articles moulés, etc.; ce polymère est principalement constitué d'un produit de réticulation de polysaccharides et (ou) de polypeptides, dont les groupes hydroxyle, amino, imino, thiol et (ou) carboxyle proviennent au moins partiellement d'une réaction non radicalaire avec des agents renfermant des groupes réticulables dans une étape postérieure à la dérivatisation, suivie de leur séparation.
