  • Fluids having silicone groups and organic groups containing esters
    Patent number: 7906671
    Abstract: A silicone composition having the formula: 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 and a reverse ester thereof; provided that if R1 is anything but methyl or ethyl, then R2 must be a methyl, ethyl or butyl.
