Economic Interdependence within ASEANes, flexible foams, and semi-rigid or rigid foams. Lignin with hydroxyl groups on its structure could be used as a substitute for polyol in the synthesis of polyurethane. Lignin can be incorporated in polyurethane without pre-treatment or with chemical modifications, e.g., oxypropylation, esterifica

Introduction: Woolfian Resonances,e abundant availability and unique structure of lignin make it a potential feedstock for the synthesis of biochemicals and biopolymers such as surfactants/dispersants, carbon fibers, phenolic resins, epoxy resins, and polyurethane resins, etc.

Degradation of Lignin by Pyrolysis,and polymers. Lignin has a complex structure, and hence a large number of pyrolytic components are generated during the pyrolysis process. The composition of the pyrolytic products depends on the type of lignin, temperature, types of catalyst, and the design of the pyrolysis reactor. It was suggeste
