    Abstract: composición de agente de revestimiento que comprende al menos un compuesto de la fórmula general (I): en la que - R1 representa un resto con al menos un átomo de carbono, y el radical libre R1* correspondiente a R1 puede iniciar una polimerización a través de radicales de mónomeros insaturados, - los restos R2, R3, R4, R5, R6, R7 para grupos alquilo iguales o diferentes, de cadena lineal o ramificados, substituidos o no substituidos, representan grupos aralquilo, alquilarilo o arilo substituidos o no substituidos, pudiendo ser -CR2R3 y/o -CR6R7 parte de una estructura cíclica, - los restos R4 y R5 para grupos que contienen ciano, éter, hidroxi, nitro o carbonilo, o R4CNCR5, representa una parte de una estructura cíclica substituida o no substituida, en la que se puede condensar al menos otro anillo saturado o insaturado, o - -CR2R3R4 o -CR5R6R7 son parte de un anillo aromático; o al menos un compuesto de la fórmula general (Ia): en la que - R1 representa un resto con al menos un átomo de carbono, y el radical libre R1* correspondiente a R1 puede iniciar una polimerización a través de radicales de mónomeros insaturados, - R8 y R9 representan hidrógeno, grupos alquilo iguales o diferentes, de cadena lineal o ramificados, substituidos o no substituidos, grupos aralquilo, alquilarilo o arilo substituidos o no substituidos, que pueden poseer un carácter polímero, - al menos dos de los restos R9 son un resto fenilo o un resto fenilo substituido; o una mezcla de dos o más de los mismos, y ácido p-toluenosulfónico.

    Abstract: Trimethylolpropane esters are new. Trimethylolpropane esters are of formula (1). (1) AO : OCH2CH2, OCH2CH(CH3), OCH(CH3)CH2, n1-n3 : 4-6; n1+n2+n3+n4 : 14-16; m1-m3 : 1-3; m1+m2+m3 : 4-6; R1-R3 : 4-6 Independent claims are included for: (1) a process for the production of esters of formula (1) by reaction of alkoxylated trimethylolpropane with (meth)acrylic acid in the presence of at least one esterification catalyst (C) and at least one polymerization inhibitor (D) as well as optionally a solvent (E) that forms an azeotrope with water; optionally removal of at least a portion of the water from the reaction mixture during or after the water from the reaction, optiionally neutralizing the reaction mixture; optionally removing the solvent if present by distillation and/or stripping with an inert gas; (2) across-linked hydrogel prepared by polymerization of an ester of formula (1) with (meth)acrylic acid with optionally additional monoethylenicaly unsaturated compounds (N) as well as optionally at least a further copolymerizable hydrophilic monomer (M) in the presence of at least one radicatl initiator (K) and optionally a graft base (L); optionally cross-linking of the resulting reaction mixture; drying of the reaction mixture and optionally grinding the reaction mixture; (3) a mixture comprising 0.1-40 wt.% of a ester of formula (1) and (meth)acrylic acid, 0.5-99.9 wt.% of a hydrophilic monomer (M), 0-10 wt.% of an esterification catalyst (C), 0-5 wt.% polymerization inhibitor (D) and 0-10 wt.% sovlent (E).

    Abstract: The present invention relates to novel mixtures of (meth)acrylic esters of polyalkoxylated trimethylolpropane of the formula 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 ester mixtures and the use of reaction mixtures thus obtainable.
