Research Abstract

In order to convert the residual lignin generated during bioethanol production using lignocellulosic materials into functional materials for environmental conservation, hydrothermal treatment with alkali was conducted followed by co-polymerization was occurred with acrylic acid. However, the co-polymerization was not succeed because of poor compatibility between the lignin and acrylic acid. The lignin was co-polymerized withε-caprolactone to obtain the functional polymer with high swellability. The solubilization mechanism of residual lignin by hydrothermal treatment was investigated.
