| Résumé : |
Alkyd resins are typically produced by the condensation polymerisation of natural oils or fatty acids with polyhydric alcohols such as pentaerythritol, glycerol or trimethylolpropane, and dibasic acids such as phthalic anhydride and isophthalic acid. Since natural oils and fatty acids are renewable raw materials and polyhydric alcohols can be produced fully or patly from renewable raw materials, alkyd resins represent a very "green" binder selection compared with acrylic binders, whose building blocks are currently derived from mineral oil. |
