A silicone composition having the formula (I) wherein R1 are independently selected from the group consisting of: an alkyl having 1-5 carbon atoms, a substituted alkyl having 1-5 carbon atoms optionally substituted by one or more fluorine atoms, and a phenyl, and R2 is selected from the group consisting of: hydrogen, alkyl of 1 to 45 carbon atoms, substituted alkyl of 1 to 45 carbon atoms optionally substituted by one or more fluorine atoms, aryl, a partially esterified ester-containing group represented by the formula (II) and a reverse ester thereof represented by the formula (III) and the formula (IV), and a reverse ester thereof represented by the formula (V) provided that if R1 is anything but methyl or ethyl, then R2 must be a methyl, ethyl or butyl.

L'invention concerne un fluide ayant des groupes silicone et des groupes organiques contenant des esters. Une composition de silicone ayant la formule (I) dans laquelle les R1 sont choisis indépendamment dans le groupe constitué par : un alkyle ayant 1-5 atomes de carbone, un alkyle substitué ayant 1-5 atomes de carbone facultativement substitué par un ou plusieurs atomes de fluor, et un phényle, et R2 est choisi dans le groupe constitué par : hydrogène, alkyle ayant 1 à 45 atomes de carbone, alkyle substitué ayant 1 à 45 atomes de carbone facultativement substitué par un ou plusieurs atomes de fluor, aryle, un groupe contenant un ester partiellement estérifié représenté par la formule (II) et un ester inverse de celui-ci représenté par la formule (III) et la formule (IV), et un ester inverse de celui-ci représenté par la formule (V) à la condition que si R1 est tout sauf méthyle ou éthyle, R2 doit être un méthyle, éthyle ou butyle.
