Abstract

Producing polyurethanes by polymerizing polymeric isocyanate, polyol and kraft lignin or some other type of technical lignin, in which the lignin used has been freed substantially of its high molecular weight fractions by means of some suitable method herefor. The polyurethane produced exhibits good mechanical properties and high thermal stability.
