Carboxy-substituted organosilicon stabilizers for a silicate-containing antifreeze
Abstract
Abstract Novel substituted organosilicon carboxylates characterized by the following formula: <IMAGE> wherein M is a monovalent cation: Z represents a moiety hydrolyzable to silanol; R1 represents hydrogen, a monovalent hydrocarbon radical such as methyl, ethyl, phenyl, and the like or a substituted monovalent hydrocarbon radical; a has a value from 0 to 20, b has a value of 1 or 2, c has a value of 0 or 1, n has a value of 2, 3, or 4 and m has a value of from 3 to 15 when a is other than 0 and from about 7 to about 15 when a is 0, are disclosed as useful to provide a silicate-containing antifreeze having enhanced dilute aqueous stability, as are precursors which are convertible to such carboxylates upon addition to base and water, such precursors having the formula: <IMAGE> wherein Y is a member selected from the group consisting of <IMAGE> <IMAGE> <IMAGE> the other constituents and values being as described in conjunction with the organosilicon carboxylates; also disclosed are copolymers formed by reacting such carboxylates with an organic or inorganic silicate.
