Resumen:
Xylitol is a monomeric polyol that contains five reactive hydroxyl (OH) groups in its molecule. Usually, monomeric polyols with two OH groups (diols) are used as a chain extender in the production of polyurethanes whereas those with three or more OH groups are used as initiators for polyether production or crosslinker for polyurethane production. Linear polyester polyols are produced by condensation polymerization of dicarboxylic, esters or anhydrides with diols. Bio-based polyols from vegetable oils, lignocellulosic biomass, and proteins have been studied for the production of bio-based polymers. Vegetable oils are used for bio-based polymers for foams, coatings, adhesives, others. The aim of this work was obtaining formulations of wood coatings based on alkyd emulsion from vegetal oils and xylitol, and their application in wood samples.
