FIELD: organic chemistry, chemical technology, polymers.
SUBSTANCE: invention relates to novel polyalkoxylated trimethylolpropane (meth)acrylic esters. Invention proposes polyesters of the following formulas (Ib) 
and (Ic) 
wherein EO means O-CH2-CH2-; PO means independently of one another O-CH2-CH(CH3)- or O-CH(CH3)-CH2-; n1 + n2 + n3 = 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, 54, 55, 56, 57, 58, 59 or 60; m1 + m2 + m3 = 4, 5, 6, 7, 8, 9, 10, 11, 12 or 13; R1, R2 and R3 mean independently of one another hydrogen atom (H) or -CH3. Proposed esters can be used in preparing polymers absorbing aqueous liquids and forming hydrogel. Invention provides development of compounds that can be used as radical cross-linking agent, in particular, for superabsorbers.
EFFECT: valuable properties of esters.
