NOVEL AMPHIPHILIC COPOLYMER-TYPE BIODEGRADABLE SURFACE ACTIVE AGENTS COMPRISING HYDROPHOBIC SEGMENTS AND OLIGO- AND/OR POLYSACCHARIDES

摘要

The invention relates to the use of at least one block copolymer as a surface active agent, said block copolymer having a linear and/or branched structure consisting of a segment comprising a natural or modified oligo- and/or polysaccharide sequence and at least one hydrophobic sequence made up of bioerodable polymers having general formula (I), wherein X denotes a CN or CONHR radical, Y denotes a COOR' or CONHR'' radical, with R, R' and R" denoting, independently of one another, a hydrogen atom, a linear or branched C1 to C20 alkyl group, a linear or branched C1 to C20 alkoxy group, an amino acid radical, a mono- or polyhydroxylated acid radical or a C5 to C12 heteroaryl or aryl radical.
