Abstract
Lignin and polyether glycol produces a product which has a distinct melt point and melt viscosity. Polyether glycol has a plasticizing effect wherein the lignin can be thought of as the hard resin. When 20 parts of polyether glycol are processed with 80 parts of lignin a new material which has a melt point and a viscosity is created whereas lignin itself has no melt and flow characteristics. The new modified lignin can be cured with hexamine like a phenolic resin.
