Abstract
(DE)
Ein biologisch abbaubarer, polymerer Werkstoff ist gekennzeichnet durch mindestens ein Polysaccharid und/oder ein Derivat eines Polysaccharides sowie mindestens durch zwei weitere Polymere mit unterschiedlicher Kristallinität, welche keine vollständige Mischbarkeit miteinander aufweisen. Dabei weist mindestens eine der Polymerkomponenten vorzugsweise eine hohe Kristallinität auf. Im weiteren ist das Polysaccharid oder Derivat davon mit mindestens einer der zwei weiteren Polymerkomponenten wenigstens nahezu homogen mischbar.
(EN)
The invention relates to a biodegradable polymer material which is characterized by at least one polysaccharide and/or polysaccharide derivative and at least two other polymers of different crystallinity which are not fully miscible. At least one of the polymer components is preferably of high crystallinity. Moreover, the polysaccharide or polysaccharide derivative is at least almost homogeneously miscible with at least one of the two additional polymer components.
(FR)
L'invention concerne un matériau polymère biodégradable qui se caractérise par au moins un polysaccharide et/ou un dérivé d'un polysaccharide, ainsi qu'au moins par deux autres polymères d'une cristallinité différente qui ne peuvent pas se mélanger complètement l'un avec l'autre. Au moins un des composants polymères présente, de préférence, une cristallinité élevée. En outre, le polysaccharide ou son dérivé peut être mélangé de façon au moins presque homogène avec au moins un des deux autres composants polymères.
