2. On the primary amine, secondary amine, and other groups, by further grafting other reactive groups, modification can make it obtain more excellent properties on the original basis.
3. The newly developed derivatives together form a water-soluble polymer product with independent, complete, and distinctive characteristics.
4. Applications in coatings, inks, adhesives, fiber treatment, sewage treatment, textile printing and dyeing, biomedicine, etc.
