  • Method for producing hydrophilic monomers and uses thereof
    Patent number: 6464850
    Abstract: The invention relates to a method for producing hydrophilic monomers which are particularly useful for electrophoresis and to electrophoresis compositions and coating compositions. The electrophoresis gel compositions and electrophoresis polymer compositions are hydrolytically stable and have high resolution. The method uses the steps of reacting a (meth)acryloyl with an aminoalcohol in the presence of a base in a polar solvent, optionally filtering an aqueous solution of the reaction product, deionizing an aqueous solution of the reaction product, and removing the solvent.
    Type: Grant
