The invention relates to novel mixtures of polyalkoxylated trimethylolpropane (meth)acrylate of formula (I), wherein AO independently represents EO, PO, or BO for each AO, EO representing O-CH2-CH2-, PO independently representing O- CH2-CH(CH3)- or O-CH(CH3)-CH2-, BO independently representing O-CH2-CH(CH2- CH3)- or O-CH(CH2-CH3)-CH2-, p1 + p2 + p3 equals 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, and R1, R2, R3 independently represent H or CH3. Also disclosed are a simplified method for producing said ester mixtures and the use of the obtained reaction mixtures.
