    摘要: A method for making lignin-amines is provided. The method comprises providing a lignin; then modifying the lignin with modifier to create a modified lignin; and then reacting the modified lignin with an amine to form a lignin-amine. Suitable modifiers comprise acrylates. A method for coagulating suspended materials in a water stream is also disclosed. The method comprises providing a water stream and contacting the suspended materials in the water stream with at least one lignin-amine.
