NOVEL BIODEGRADABLE SURFACTANTS OF THE AMPHIPHILIC COPOLYMER TYPE COMPRISING HYDROPHOBIC SEGMENTS AND OLIGO AND / OR POLYSACCHARIDES

摘要

P The subject of the present invention is the use as surfactant of at least one block copolymer with a linear and / or branched block structure composed of a segment comprising a natural or modified oligo- and / or polysaccharide sequence and at least one hydrophobic sequence consisting of bioerodible polymers of general formula (I): in which: - X represents a CN or CONHR radical, - Y represents a COOR 'or CONHR "radical with R, R' and R" representing, independently one of the other, 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 polyhydroxy acid radical or a radical C5 to C12 aryl or heteroaryl. / P
