Abstract
Epoxy resins were prepared from hydroxyalkyl lignin derivatives with varying degrees of alkoxylation. The epoxy-functional copolymers were fractionated into narrow molecular weight, chemically uniform prepolymers with good solubility. The epoxy resins were cured with diamine, and the network polymers were characterized by mechanical testing. Modulus and ultimate strength increased with lignin content and ultimate strain decreasing. The resins were comparable or superior to diglycidyl ether of bis-phenol A (DGEBA)-based (control) resins in strength.Keywords
