| titleOfInvention | Uv-absorbing quaternary polysiloxanes |
| abstract | Ultraviolet absorbing quaternary polysiloxanes of specific formula, are new. The siloxanes contain quaternary nitrogen moieties which contain monovalent chromophore residues responsible for UV absorption. <??>UV absorbing quaternary polysiloxanes of formula (I) are new. <??>R<1> = 1-4C lower alkyl or phenyl; <??>R<2> = partially the same R<1>, with the remainder being of formula (Ia). The average molecule has ≥ 1 residue of formula (Ia); <??>a = 1-200; and <??>b = 0-10. <??>-M-Z<+>A<-> (Ia) <??>M = divalent ≥ 4C hydrocarbon with an OH group, interrupted by ≥ 1 oxygen atoms. The N-atom of the Z residue is bonded to the M residue via the C atom adjacent to the C-OH group in the M residue; <??>Z<+> = residue of formula (Ib); and <??>A<-> = (in)organic anion, originating from a conventional physiologically compatible acid (HA). <??>R<3>, R<4> = 1-22C alkyl or 2-22 alkenyl, optionally having alkyl or alkenyl OH groups; <??>R<5> = monovalent chromophore residue responsible for UV absorption, of formula (Ic); and <??>x = 0-6. <??>R<6> = a residue; <??>R<7> = -CH=CH-; <??>R<8> = H, alkyl, haloalkyl, halo, phenyl, OH, alkoxy, amino, alkylamino, dialkylamino, di(hydroxyalkyl)amino, or di(polyalkoxy)amino; <??>m, n = 0 or 1; and <??>o = 0-5. <??>An Independent claim is also included for the preparation of (I) by reacting a compound of formula (II) with an amine of formula (IIb). The compounds are reacted in a known way in amounts that each epoxide group has at least one corresponding amino group. The reaction is performed in the presence of a conventional physiologically compatible (in)organic acid (HA), at a temperature of 40-120 degrees C. <??>R<9> = partially the same R<1>, with the remainder comprising monovalent residue, corresponding in structure to M. R<9>, instead of bonding to Z and OH, has an epoxide group. The average molecule has ≥ 1 monovalent R<9> residue. |
