STARCH COPOLYMERS AND NANOPARTICLES THEREOF FOR DRUG DELIVERY SYSTEMS

摘要

The present invention relates to starch Copolymer comprising starch as a backbone molecule, a covalently bound linker and a polymerized chain of monomers comprising at least one olefin group bound to the linker, wherein the degree of substitution of hydroxy-groups of the backbone is in the range of 0.05 to 3, a method of preparation, nanoparticles comprising the copolymers, their preparation and their use for the preparation of drug delivery systems.
