Abstract: A cross-linked composition comprises the reaction product of an organohydrogensiloxane and a cross-linker, in the presence of a hydrosilylation catalyst. The organohydrogensiloxane comprises siloxy units of average formula (I): (R43SiO1/2)(R42—SiO2/2)a(R1R4SiO2/2)b(R4HSiO2/2)c(R2R4SiO2/2)d(R3R4SiO2/2)e—(R43Si—O1/2). Each of R1 and R2 is an independently selected hydrogen atom or a substituted or unsubstituted hydrocarbyl group. R3 is a hydrogen atom or a group having at least one carboxyl group or a precursor thereof. R4 is an independently selected substituted or unsubstituted hydrocarbyl group. Further, a?0, b?0, c?1, d?0, and e?1. The cross-linker has at least two aliphatic unsaturated hydrocarbon groups. A method of forming the cross-linked composition comprises the steps of providing the organohydrogensiloxane and cross-linker, and combining the organohydrogensiloxane and cross-linker in the presence of the hydrosilylation catalyst to form the cross-linked composition.

Abstract: An aminosiloxane polymer includes at least one Si-bonded functional group. This functional group has the chemical formula: —(R—NH)aR1—N(R2)—CH(—COOH)(—R3—C(?O)—NR42) (I).
