## Abstract

The invention relates to novel polyurea- and/or polyurethane polyorganosiloxane compounds, processes for the preparation thereof, and their use and novel reactive 1- or 2-component systems and cured compositions therefrom. The compounds preferably contain repeating units of the formula (2): in the polyurea- and/or polyurethane polyorganosiloxane backbone. The polyurea- and/or polyurethane polyorganosiloxane compounds can also contain polyether segments in the backbone.

## Claims

### Claim 1

Polyurea-polysiloxane compounds consisting of at least one structural element of the formula (1):
wherein
ST1 is chosen from divalent or higher valency, straight-chain, cyclic or branched, saturated, unsaturated or aromatic, substituted or unsubstituted hydrocarbon radicals having up to 1,000 carbon atoms exclusive of the carbon atoms of an optional polyorganosiloxane unit, which can contain one or more groups chosen from —O—, —C(O)—, —NH—, —NR3—,
and a polydiorganosiloxane unit having 2 to 1,000 silicon atoms,
wherein R3 is a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 40 carbon atoms, which can contain one or more groups chosen from —O—, —C(O)— and —NH—,
and R5 is a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 100 carbon atoms, which can contain one or more groups chosen from —O—, —C(O)— and —NH—, or R5 is a divalent radical which forms cyclic structures within the radicals ST1 and/or ST2, and
ST2 is a radical of the formula (2)
wherein
ST3 is a straight-chain or cyclic or branched, saturated or unsaturated or aromatic, substituted or unsubstituted hydrocarbon radical having 2 to 100 carbon atoms, which can be substituted by —O—, —C(O)—, —NH—, —NR3—, wherein R3 is as defined above,
ST4 is a straight-chain or cyclic or branched, saturated or unsaturated or aromatic, substituted or unsubstituted hydrocarbon radical having 2 to 100 carbon atoms exclusive of the carbon atoms of an optional polyorganosiloxane unit, which can be substituted by —O—, —C(O)—, —NH—, —NR3— and by a polydiorganosiloxane unit having 2 to 200 silicon atoms, wherein R3 is as defined above, and
A− is an organic or inorganic anion,
