The invention relates to novel (meth)acrylic esters of polyalkoxylated trimethylolpropane of formula (I), wherein EO represents O-CH2-CH2-,PO represents independently from each other O-CH2-CH(CH3)- or O-CH(CH3)-CH2-,n1, n2, n3 represent independently from each other 4,5 or 6, n1 + n2 + n3 is 14, 15 or 16,m1, m2, m3 represent independently from each other 1,2 or 3, m1 + m2 + m3 is 4, 5 or 6, R1, R2, R3 represent independently from each other H or CH3. The invention also relates to a simplified method for producing said esters and the use of the thus obtained reaction mixture.
La présente invention concerne de nouveaux esters (méth)acryliques de triméthylolpropane polyalcoxylé représentés par la formule (I), dans laquelle EO représente O-CH2-CH2-, PO représente indépendamment O-CH2-CH(CH3)- ou O-CH(CH3)-CH2-, n1, n2 et n3 représentent indépendamment 4, 5 ou 6, n1 + n2 + n3 est égal à 14, 15 ou 16, m1, m2 et m3 représentent indépendamment 1, 2 ou 3, m1 + m2 + m3 est égal à 4, 5 ou 6 et R1, R2 et R3 représentent indépendamment H ou CH3. L'invention concerne en outre un procédé simplifié pour produire ces esters, ainsi que l'utilisation des mélanges réactionnels obtenus par ce procédé.
