| abstract |
An amphiphilic block copolymer having any one of the formulas D-S-H, S(D)-H, S-H(D), D-S-H-S, D-S-H-S-D, S(D)-H-S, S(D)-H-S(D) or S-H(D)-S is disclosed. S is a hydrophilic block; H is a hydrophobic block; D is a drug molecule; ( ) denotes that the group is bonded directly or indirectly as a side chain or as part of a side chain group to the adjacent group; and the hyphen, "-" (or sometimes "–"), denotes that each of the adjacent S, H or D are linked either directly to one another or indirectly to one another via a linker, additionally wherein the hydrophilic block comprises a first hydrophilic monomer and the hydrophobic block comprises a first hydrophobic monomer and a second hydrophobic monomer. |
