Sammanfattning
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 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.
