Abstract:
1. A process for preparing a solution of at least one radiation-sensitive, free-radically polymerizable organic compound, comprising: i) esterifying a) a first starting compound, which has an acid halide group, and b) a second starting compound, which has an alcoholic hydroxyl group, in a solvent or solvent mixture and in the presence of a substantially stoichiometric amount of at least one tertiary organic amine to the amount of acid halide; wherein the solvent comprises one or more ketones having a boiling point of below 150° C. under atmospheric pressure (1 bar) or the solvent mixture is composed to an extent of at least 50% by weight, based on the amount of solvent, of said ketones; and one of the two starting compounds has at least one radiation-sensitive group and the other of the two starting compounds has at least one ethylenically unsaturated, free-radically polymerizable group; and ii) separating an organic ammonium halide which forms during the reaction by adding water in an amount such as to form a substantially saturated solution of said organic ammonium halide in water, and separating said saturated aqueous solution from an organic phase.
