Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
210 words
An aminoorganosilicon acylamino compound having the formula ##STR41## wherein: X is an alkoxy radical having 1 to 6 carbon atoms; R is a divalent alkylene radical having 1 to 4 carbon atoms; R 1 is hydrogen or an alkyl radical having 1 to 4 carbon atoms; R 2 is a divalent alkylene radical having 2 to 4 carbon atoms; R 3 is a radical selected from the group consisting of hydrogen, an alkyl radical having 1 to 20 carbon atoms or a phenyl radical; R 4 is a radical selected from the group consisting of an alkyl radical having 1 to 20 carbon atoms, a phenyl radical or a silyl radical of the formula: ##STR42## wherein X, R and Rhu 1 are the same as defined above; Q is a radical selected from the group consisting of hydrogen, an alkyl radical of 1 to 4 carbon atoms, a phenyl radical or an ester radical of the formula --COOR 5 wherein R 5 is an alkyl radical having 1 to 4 carbon atoms; and wherein a has a value of 0 to 2 and t and x each have a value of 0 to 4, with the proviso that when x is at least 1, R 4 can also be hydrogen.
Claim 2
Dependent Claim
