Patent ID: 8742053

Claim:
A polyamide-polysiloxane compound containing at least one selected from the group consisting of (A) a structural element of formula (3) (B) an acid addition compound of formula (3) and (C) a salt of formula (3): wherein X is an electron-attracting group, the radicals R 6 can be identical or different and are selected from the group consisting of hydrogen and straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radicals having up to 40 carbon atoms, wherein R 6 optionally further comprises one or more groups selected from the group consisting of —O—, —C(O)—, —NH— and —NR 3 —, wherein R 3 is a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 40 carbon atoms, wherein R 3 may optionally further comprises one or more groups selected from the group consisting of —O—, —C(O)— and —NH—, and ST 1 is a divalent, trivalent or tetravalent, straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 1,000 carbon atoms, wherein ST 1 optionally further comprises one or more groups selected from the group consisting of —O—, —C(O)—, —NH—, —NR 3 — and a polysiloxane unit having 2 to 1,000 silicon atoms, subscript y is from 0 to 5, and subscript x is chosen from 1 to 3, and wherein (A) Y is selected from the group consisting of —O—, —S— and —NR 2 —, wherein R 2 is hydrogen or a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 40 carbon atoms, wherein R 2 optionally further comprises one or more groups chosen from —O—, —C(O)—, —NH— and —NR 3 —, ST 2 is a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 1,000 carbon atoms, which can contain one or more groups chosen from —O—, —C(O)—, —NH—, —NR 3 —, and a polysiloxane unit having 2 to 1,000 silicon atoms, wherein (i) R 5 is a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 100 carbon atoms, optionally further comprising one or more groups selected from the group consisting of —O—, —C(O)— and —NH—, or (ii) R 5 is a divalent radical which forms cyclic structures within the radical ST 2 , (B) Y is nitrogen and forms a heterocyclic structure together with ST 2 with the provisos that at least one of the radicals ST 1 and ST 2 comprises a polysiloxane radical and that neither ST 1 nor ST 2 includes a urethane linkage and ST 2 excludes a urea group.
