Abstract
The present invention relates to formulations for obtaining polymer materials comprising an at least difunctional reactant capable of reacting with a polyol and a polyol capable of reacting with said at least difunctional reactant, said polyol being an at least partially biobased aromatic polyol. The invention also relates to the use of said formulations for the manufacture of polyurethanes, polyesters, polycarbonates or epoxy resins, intended for the production of coatings in general, paints, elastomers, sealants and adhesives.
Claims13
A formulation for obtaining a polymer material comprising an at least difunctional reactant capable of reacting with a polyol and a polyol capable of reacting with the at least difunctional reactant, the polyol:
- being an aromatic polyol
- having a hydroxyl value of less than or equal to 200 mg KOH g−1,
- a number-average functionality of greater than or equal to 2, and
- a content of biomass-derived atoms of greater than 30%.
