Abstract:
A process for preparing poly-C2-C4-alkylene glycol mono(meth)acrylic acid esters by reacting (meth)acrylic anhydride with a poly-C2-C4-alkylene glycol carrying at least one OH group in the presence of abase having a solubility in the poly-C2-C4-alkylene glycol of not more than 10 g/l at 90° C.
