可溶于四氢呋喃的2，2-二甲基三亚甲基碳酸酯与己二酸酐的嵌段共聚物合成了[（DTC-b-AA）]（DTC/AA摩尔比为64.7/35.3，Mn = 12.3 × 104，Mw/Mn = 1.64（2，6-二叔丁基-4-甲基苯酚）催化剂在25 ℃下反应32 min。通过改变溶剂和DTC/AA的投料比，制备了AA嵌段含量为8.5%~ 50.8%的共聚物。
Abstract 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 Mw/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.
