Halogenated pref. fluorinated polyorganosiloxanes (POS) have the formula Ä(R<1>)a1(Gf)b1SiO1/2Ü-ÄR<2>GfSiO2/2Üp-ÄHR<2>SiO2/2Üy 1-Ä(R<2>)2SiO2/2Üy-Ä(R<1>)a2(Gf)b2SiO1/2Ü (I) and (II). In the formulae, (i) a1 + b1 =3; a2 + b2 = 3; a2 = 2, 3; b1, b2, = 0, 1; p = 0-200 (1-90); y1 = 0-10 (0-5); y = 0-50 (0-25); with p + y1 + y = 5-200 (10-100) and (p/(p + y + y1 + 2)Ü x 100 ≥ 3 (pref. 5); (ii) p' = 1-9 (1-4.5); (iii) y1' = 0-0.5 pref. 0.25; (iv) y' = 0-5 (pref. 0.5); (v) R1-2 = 1-12C (1-6C) aryl, aralkyl, alkylaryl (opt. branched); (vi) (Gf)= -(Z1)h-(Z2)g-Ä(Z3)j-RfÜk with h = 0.1; g = 0.1; j = 0.1; and k = 1 or 2; ≥ 1 Gf gp. is present in POS p; Z1= -(CmH2m)-with m ≥ 2 and, if m = 2 then g > 0 in ≥ 1 Gf; Z2 = -W(-C(O)-)2, -CRa(-C(O)-)2, -W(OH)-, -ÄW-NH-COÜ-, -ÄW-C(O)-Ü-, -Si(R6)< (where R6 = H or 1-6C alkyl), or gp. (x)-(y), in each case, one free valency is attached to Rf and the other to hydroxyl or 1-6C alkoxy; W = cyclic or non-cyclic hydrocarbon radical pref. aliphatic, alkenyl, alkynyl or aromatic; Z3 = -U-CnH2n- with n ≥ 1, U = S, NH, NHSO, and pref. O; and Rf = -CqF2q-CF3, q ≥ 0; or -CqF2q-H, q ≥ 1; or -NRrfSO2CqF2q-CF3, q ≥ 0, Rrf = H, aryl, 1-6C alkyl; or NRrfSO2CqF2q-H, q ≥ 1. |
