摘要： Microparticles with a uniform spherical shape and a very narrow size distribution are described. They consist wholly or partly of a linear water-insoluble polysaccharide, preferably of 1,4-&agr;-D-polyglucan, and may contain other, in particular biodegradable, polymers and/or active substances. They are suitable inter alia for the controlled delivery of active substances. They are prepared by dissolving 1,4-&agr;-D-polyglucan or the polysaccharide in a solvent, introducing the solution into a precipitant, cooling the mixture and removing the particles formed.

摘要： Thermoplastic mixture based on biopolymers for producing shaped biodegradable articles with improved properties, preparation of the mixture, and also its use. A novel thermoplastic mixture based on biopolymers, in particular on starch, features the presence of lignin and is used for producing shaped biodegradable articles with improved properties, preferably with improved mechanical properties. The mixture is preferably obtained by preparing, and mixing with one another, A) 100 parts by weight of one or more physiologically nonhazardous, biodegradable, thermoplastically processable polymeric materials selected from the group consisting of polysaccharides and proteins, preferably at least one starch of any type which is native, chemically modified, fermentative, recombinant and/or prepared by biotransformation, and/or derivatives of the starches mentioned; B) from 10 to 100 parts by weight of water; C) from 1 to 100 parts by weight of lignin; D) if desired, up to 50 parts by weight of at least one plasticizer; and E) if desired, up to 200 parts by weight, preferably not more than 100 parts by weight, of other conventional additives; where the components are thermoplastified with introduction of thermal and mechanical energy into the mixture, preferably at an elevated temperature and with simultaneous exertion of shear forces onto the mixture. Surprisingly, the use of lignin with thermoplastic materials based on biopolymers, in particular based on starch, leads to improved thermoplastic materials which have advantages in particular in terms of their mechanical properties or other performance characteristics.

摘要： The present invention relates to a method for preparing smooth-surface spherical microparticles which are completely or partially made of at least one water-insoluble linear polysaccharide. This method involves dissolving the at least one water-insoluble linear polysaccharide in a solvent or a mixture of solvents, introducing the solution into a precipitation agent or a mixture of precipitation agents, optionally cooling the mixture thus obtained, and separating the microparticles thus formed. The precipitation agent used consists of at least one water-soluble cellulose derivative. This invention also relates to microparticles obtained according to this method.
