摘要：

A series of biodegradable multifunctional hyperbranched-linear-hyperbranched barbell-like copolymers(HLHCs) were prepared by poly(ethylene glycol) (PEG), D, L-lactic acid (D, L-LA) and 2,2-Bis(hydroxymethyl)propionic acid(BHP AB(2)-type monomer) under bulk condition. The branching density of the hyperbranched section were varied by controlling the molar ratio of BHP to hydroxyl-terminal groups of PEG. The copolymers were characterized by 1H-NMR, 13C-NMR, GPC.
