Résumé : |
Several plant-based alternatives to fossil fuel-based (meth)acrylate monomers are available. Most promising types include the diesters of itaconic acid and esters of (meth)acrylate monomers prepared with plant-based alcohols. Other plant-based monomers show issues with either too slow, or too high reactivity, or with lacking commercial availability. Applying the preferred and commercial available monomers in emulsion polymerisation can yield water-based and partially plant-based binders showing film properties in industrial coatings that are similar to those found for paints based on commercially available fossil-fuel based binders. At this point in time, polymeric binders with plant-based contents of around 40% can be achieved (calculated on total carbon content). New developments with even higher plant-based contents are, however, foreseen to be available within five years from now. |
