A dihydroxyl-terminated polylactide oligomer(HO-PDLLA-OH) was synthesized from D,L-lactic acid and 1,4-butanediol through polycondensation and subsequently converted to the dibromo-terminated PDLLA analogue(Br-PDLLA-Br) by reaction with 2-bromopropanoyl bromide The products were characterized by means of IR and 1H-NMR spectroscopy.
以D,L-乳酸和1,4-丁二醇为原料,采用缩合聚合法合成了双端羟基聚乳酸(HO-PDLLA-OH),然后与α-溴代丙酰溴反应,得到适于ATRP的含溴端基的聚乳酸大分子引发剂Br-PDLLA-Br。
