以乳酸为单体,采用先缩聚后解聚的方法制备了L-丙交酯。英文名称:polycondensation;condensation polymerization一种或几种含有二个或以上官能团的单体有机物化合成为聚合物同时析出低分子副产物(如水、卤化氢等小分子)的过程。例如二元酸和二元胺经缩聚而成聚酰胺,同时生成水。缩聚反应的特点是:大多数为可逆反应和逐步反应,分子量随反应时间的延长而逐渐增大,但单体的转化率却几乎与时间无关。根据反应条件可分为熔融缩聚反应、溶液缩聚反应、界面缩聚反应和固相缩聚反应四种;根据所用原料可分为均缩聚反应、混缩聚反应和共缩聚反应三种;根据产物结构又可分为二向缩聚或线型缩聚反应和三向缩聚或体型缩聚反应两种。
