A method of producing prepolymeric materials from lignin is disclosed. The method uses lignin which has been hydroxyalkyl modified, such that the lignin is substantially non-phenolic and solvent soluble and/or liquid. The modified lignin is reacted with materials which yield prepolymers which may be polymerized according to known methods to produce useful polymers.
