A method for producing radically polymerizable carboxylic acid esters by reacting ethylenically unsaturated carboxylic acids, carboxylic acid anhydrides, or carboxylic acid halogenides (collectively referred to as carboxylic acid components) with a hydroxyl compound comprising at least 60 weight-% C2- to C4-alkoxy groups (referred to in short as a polyalkoxy compound), characterized in that the reaction occurs in the presence of a polymerization inhibitor and a reducing agent.
Procédé de fabrication d'esters d'acide carboxylique pouvant subir une polymérisation radicalaire, par transformation d'acides carboxyliques, d'anhydrides d'acide carboxylique ou d'halogénides d'acide carboxylique éthyléniquement insaturés (désignés brièvement composants d'acide carboxylique) avec un composé hydroxyle qui est constitué pour au moins 60% en poids de groupes alcoxy C2 à C4(désigné brièvement composé polyalcoxy). Selon l'invention, la transformation s'effectue en présence d'un inhibiteur de polymérisation et d'un agent de réduction.
