在不互溶的两种液体苯和水中添加第三种物质:甲醇,可以得到稳定的乳浊液。这第三种物质叫乳化剂。高分子体系中,也有同样的现象。在高分子体系中,和乳化剂相当的第三种物质叫相溶化剂。不同种类的高分子聚合物之间的关系犹如苯和水的关系一 In the two immiscible liquid benzene and water to add a third substance: methanol, can be a stable emulsion. This third substance is called emulsifier. Polymer systems, there are the same phenomenon. In the polymer system, and emulsifier equivalent to a third substance called compatibilizer. The relationship between different kinds of polymers is like the relationship between benzene and water
