Description	Journal: Iop Conference Series: Earth and Environmental Science Poly (DL-lactide)/Poly (Ethylene Glycol) Diblock Copolymer is successfully synthesized with mPEG and DL-LA as main raw materials. FT-IR, 1H-NMR and DSC are used to study the influence of precipitant species and dosage on the properties of copolymer; and the effects of the m (mPEG)/m(LA)’s ratio on the copolymer’s molecular weight (Mn), glass transition temperature (Tg) and the properties of residual monomers. The results showed that the precipitant was ether, dichloromethane / ether was 1/6, m (m PEG)/m (LA) was 2/1.8, the synthesized Poly (DL-lactide)/Poly (Ethylene Glycol) Diblock Copolymers, the residual monomer was only 0.26 and the solvent residue was only 0.04.
