The present invention relates to novel (meth)acrylic esters of polyalkoxylated trimethylolpropane of the formula ##STR00001## where AO is for each AO independently at each instance EO, PO or BO where EO is O--CH2-CH2- PO is independently at each instance O--CH2-CH(CH3)- or O--CH(CH3)-CH2- BO is independently at each instance O--CH2-CH(CH2-CH3)- or O--CH(CH2-CH3)-CH2- p1+p2+p3 is 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74 or 75, R1, R2 and R3 are independently H or CH3, a simplified process for preparing these esters and the use of reaction mixtures thus obtainable.
