Biodegradable copolymer hydrogels

摘要

Biodegradable copolymer hydrogels are provided. The biodegradable copolymer hydrogels have a structure of Formula (I) or Formula (II)
, wherein, A comprises a hydrophilic polyethylene glycol polymer (A); B comprises a hydrophobic polyester polymer (B); BOX is bifunctional group monomer of 2, 2'-Bis(2-oxazoline) and used for coupling the blocks A-B or B-A-B; and n is an integer, equal to or greater than 0.
