界面缩聚,在常温及常压进行。许多在高温不稳定因而在熔融缩聚中不能用的单体,可用这一方法順利地进行缩聚,这样就扩大了缩聚单体的范围。同时,界面缩聚,设备比较简单,对单体纯度的要求并不十分严格,反应进行迅速又比较容易得到高分子量的聚合物。因此这一反应对高聚物的合成,提供了一个很便利的方法,丰富了高聚物的类型,可以说是高分子化学的一个新发展,具有广阔的前途。常見的缩聚高分子也可以应用以这一反应来制备。
Polycondensation interface, at room temperature and atmospheric pressure. Many of the monomers that are unstable at high temperatures and therefore not useful in melt polycondensation can be successfully polycondensed by this method, thus expanding the range of polycondensation monomers. At the same time, the interface polycondensation, the equipment is relatively simple, the purity of the monomer is not very strict requirements, the reaction is fast and relatively easy to get high molecular weight polymer. Therefore, this reaction provides a very convenient method for polymer synthesis, enriching the type of polymer, so it can be said that a new development of polymer chemistry, has a bright future. Common polycondensation polymers can also be used to prepare this reaction.
