摘要： Ligning and polyether glycol produces a product which has a distinct melt point and melt viscosity. This has a plasticizing effect wherein the polyether glycol 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.

摘要： Certain lignins which are readily available from pulping processes function as a polyol component of an isocyanate system to make foams and urethane plastics. Use of the lignin in this manner provides moisture and flame resistance and produces products having sufficient rigidity. The sodium level must be controlled so that the reaction between the hydroxyl groups and the isocyanates produces products with the optimal properties.
