Amphiphilic copolymer, containing at least a hydrophilic chain segment (A) and a hydrophobic chain segment (B), wherein the hydrophilic chain segment (A) contains peptides and wherein the hydrophobic chain segment (B) contains acetal groups or orthoester groups. The hydrophilic chain segment (A) preferably contains glutamine/glutamic acid units or asparagines/aspartic acid units, making a biodegradable copolymer which can form a thermogel. |
