Organosiloxanes with SiC-bonded groups and a process for preparing the same - Patent US4207246(A)

Filed: Feb 26, 1979

Published: Jun 10, 1980

Abstract

This invention relates to organosiloxanes which have SiC-bonded ester groups and contain at least one unit of the general formula: ROOCCH2CH(COOR)CH2CHR'CH2Si(CH3)aO3-a/2 in which R represents the same or different monovalent hydrocarbon radicals having from 1 to 12 carbon atoms, which are free of aliphatic unsaturation and which may contain one ether oxygen atom; R' represents hydrogen or a methyl group (CH3) and a is 0, 1 or 2. These organosiloxanes can be prepared by hydrolyzing or co-hydrolyzing silanes of the general formula: ROOCCH2CH(COOR)CH2CHR'CH2Si(CH3)aX3-a, where R, R' and a are the same as above and X represents the same or different hydrolyzable atoms or groups. Also, they may be prepared by the addition of a diester of allyl succinic acid and/or methallyl succinic acid to an organosiloxane containing Si-bonded hydrogen. These new organosiloxanes may be used as lubricants for inorganic and organic fibers, metal surfaces and as hydraulic fluids.
