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). In Formula (I), R is a C1-C10 hydrocarbon group. R1 is a C1-C10 hydrocarbon group. R2 is a hydrogen atom, a C1-C12 hydrocarbon group, or a phenyl group. R3 is a C1-C4 hydrocarbon group. Each R4 is independently a hydrogen atom, a C1-C12 hydrocarbon group, a C1-C12 hydroxyl-hydrocarbon group, or a phenyl group. Moreover, “a” is 0 or 1, such that (R—NH) is optional. The aminosiloxane polymer can be formed using the method of this disclosure and can be formed in, and/or included in, the emulsion of this disclosure.
