摘要
国内外对大分子物质物理场降解进行了比较多的研究,大分子物质降解产物均一度是热点问题,目前对于大分子物质降解主要采用的方法是化学法和酶法,但是由于化学方法不易定向控制,后期处理比较麻烦,而专一性酶较难制备,成本也高,不利于工业化广泛的生产,物理场成本低,化学试剂用量少,有着不可替代的优点。
The latest researches about degradation of macromolecules in physical fields both at home and abroad have been reviewed.The problem of homogeneity of degradation products of macromolecules is a hot issue.The main methods for degradation of macromolecules are chemical and enzymatic.However,the direct control of chemical methods is not easy,and the post-processing is cumbersome.The preparation of specific enzymes are even more difficult and expensive,so they can not be widely used in industrial production.The physical methods have irreplaceable advantages,such as low cost and less reagents.
