Abstract (en)
[origin: US2010274042A1] A process for preparing (meth)acrylic esters (E) of alcohols (A) comprising polyalkoxy groups, in which alcohols (A) which comprise polyalkoxy groups and are of the formula (I) RO—[(CH2)mO]n—H (I) in which m is an integer from 1 to 10, n is an integer from 1 to 100 and R is a straight-chain saturated or unsaturated alcohol having 1 to 30 carbon atoms, are transesterified with at least one (meth) acrylic ester (D) in the presence of at least one inorganic salt (S).
