<p>The present invention relates to a process for the preparation of polysaccharide esters of ethylenically unsaturated acids. The esterification of polysaccharides is performed under anhydrous or semi anhydrous conditions by heating homogenised mixtures of polysaccharides and acidic monomers. Moreover, the invention relates to the use of thus prepared ethylenically unsaturated polysaccharide esters in coating formulations etc. and as the building blocks of polysaccharide hybrid co-polymers, to the preparation of the said co-polymers and the co-polymers themselves.</p> |
