摘要
In general the present invention relates to polyurethanes based on the reaction of (a) a disocianate composition with (b) depolymerized lignin containing lignin-derived monomers, or the products of their respective functionalization; (c) a polyol composition, if desired (d) chain extenders, if desired, (e) additives, if desired. More specifically, this process relates to the use of depolymerized lignins containg variying amounts of 4-hydroxylalkylphenols or 4-alkylphenols and their derivatives. The polyurethanes can be partially or fully bio-based. Furthermore, the invention relates to a method for preparing these polyurethanes and to their use.
