摘要：以化学高分子的理论和技术为基础,对相关聚合物进行标的研制和改性.标的合成主要方法:①聚合(共聚)、缩聚、交联;②嵌段、接枝;③引入特性官能团、组分;④利用物性互补或控制相关相态和分散态合成新聚合物以及采用特定加工技术以得到改性效果.
On the basis of chemical macromolecular theories and technologies, research works with special modification targets have been done on relative polymers. The ways adopted are as follows: polymerization, copolymeriza-tion, polycondensation, cross - linking, inlaying segments, taking branch, inducting functional group and components, using mutual complementarity of physical natures, controlling the relative phase and dispersion state, and adopting specified process and technology.
