BLOCK-STRUCTURE COPOLYMER CONSISTING OF A SACCHARIDE SEGMENT BOUND TO AT LEAST A BIODEGRADABLE HYDROPHOBIC SEGMENT, AND CORRESPONDING PARTICLES

摘要

The invention concerns a block-structure copolymer consisting of a hydrophilic saccharide segment and at least a biodegradable hydrophobic segment of general formula (I), wherein: X represents a CN or CONHR radical; Y represents a COOR', CONHR'' radical with R, R' and R'' representing, independently of each other, a hydrogen atom, a linear or branched C1-C20 alkyl group, a linear or branched C1-C20 alkoxy group, an amino acid radical, a monohydroxylated or polyhydroxylated radical or a C5-C12 aryl or heteroaryl radical, said saccharide segment being bound either by one of its ends to a single segment of general formula (I), or by each of its two ends, to a segment of general formula (I), the two hydrophobic segments being identical or different. The invention also concerns particles based on said copolymer and a corresponding preparation method.
