(Meth)acrylic copolymer emulsions for use in coatings containing plant-based monomers

摘要

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.
