Abstrakt

Synthesis of lignopolyurethane foams based on wastes from biochemical industries, both freshly obtained
technical-grade hydrolytic lignins and those stored in dumps for a long time, was studied. It was found out that the
lignopolyurethane foams obtained have high heat-insulating properties conforming to the standards of heat-insulating
materials. It was shown for the fi rst time that prolonged storage under atmospheric conditions of technical-grade
hydrolytic lignin contained in lignopolyurethane foams has no signifi cant effect on their physicomechanical properties
