While the content of free rosin acid in the dispersed rosin sizes is high, the sizing effect is better. 而分散松香胶中游离松香含量高，分散越好，施胶的效果越佳。
In this paper, preparation techniques of cationic dispersed rosin size based on polymeric emulsifying and dispersing agents were preliminarily reviewed. 该文介绍了基于聚合物类乳化与分散剂的阳离子分散松香胶的制备技术的基本状况。
