摘要：
Tetrahydrofuran-soluble block copolymer of 2,2-dimethyltrimethylene carbonate with adipic anhydride [poly(DTC-b-AA)] containing 64.7/35.3 DTC/AA in molar ratio with Mn of 12.3×104 and M w/Mn of 1.64 was synthesized by lanthanum tris(2,6-di-tert-butyl-4- methylphenolate) catalyst at 25 °C in 32 min. The copolymer was characterized by SEC, 1H NMR and DSC. Copolymers with AA block from 8.5 % to 50.8 % were prepared by changing the solvent and feeding ratio of DTC/AA.
