<B> POLYMERIC MATERIALS LIKE STAMBLE FILLING AND THEIR PREPARATION <D> The present invention relates to expandable polymeric materials comprising a synthetic polymer, or copolymer, comprising a carboxylic group, and a biopolymer, which are suitable for bio-applications. Because of their ability to expand, polymeric materials are suitable for use as stomach fillers, to treat an overweight or obese individual, or to induce the feeling of being satiated. Methods for preparing expandable polymeric materials, which comprise aqueous reaction systems, are also described. |
