| 摘 要： | 以单苄撑缩季戍四醇为前体，合成了一端为α-溴代丙酸酯，一端为羟基的双官能引发剂。以此引发剂，先引发脂肪酶催化的甲基环碳酸酯开环聚合（ ROP）反应，再进一步在CuCl/2，2’-bpy催化下于同一反应器中串联引发苯乙烯的原子转移自由基聚合（ ATRP）。利用温度的变化，在同一反应器中进行了两种不同的反应。对不同反应条件下所得聚合产物进行了GPC，1 HNMR，13 CNMR测试。

| Abstract: | This work is directed towards developing a new method for the synthesis of block copolymers combining enzymatic ring opening polymerization （ ROP） and atom transfer radical polymerization （ ATRP） , by using a bifunctional initiator gained from the combining a primary alcohol and α-bromoester .The ROP of trimethylene carbonate （ TMC） is carried out in bulk by using No-vozym-435and ATRP of styrene catalyzed by CuCl/2,2’-Dipyridyl.Block copolymers comprising poly （TMC） and poly（styrene） block are obtained in two consecutive polymerization steps and in a one-pot cascade approach without intermediate transformation . The polymers obtained in different conditions are analyzed by 1 HNMR, 13 CNMR and GPC. |
