Carrier-bound light stabilizers and antioxidants as filler and stabilizers

摘要

Cpds. of formulae (I) -(IV) fixed on a support are claimed. The use of the cpds. as fillers, and stabilisers for organic materials against oxidative, thermal or light-induced breakdown esp. as heat stabilisers for thermoplastic polymers and the organic compsns. contg. the cpds. are also claimed. R1,R2 =1-16C alkyl, 5-12C cycloalkyl, Ph or 7-9C phenylalkyl; R4,R5 = R, 1-20C alkyl, Ph or naphthyl opt. substd. with 1-4C alkyl, NH4 or Mr+/r; R6 = H, 1-18C alkyl, 5-12C cycloalkyl, 7-9C phenylalkyl, NH4 or Mr+/r; R7 = 1-18C alkyl, Ph opt. substd. wit 1-4C alkyl, or -(CH2)q-COOR6; R8 = 1-8C alkyl; R9 = H, 1-8C alkyl, O degrees (sic), OH, NO, -CH2CN, 1-18C alkoxy, 5-12C cycloalkyloxy, 3-6C alkenyl or alkynyl, 1-8C acyl, or 7-9C phenylalkyl opt. substd. on the Ph ring with 1-4C alkyl; R10 = -COX5COOR6, glycidyl or -X6COOR6; R11 = H or 1-18C alkyl; R12 = 1-18C alkyl or 2-14C alkenyl; R13 = H or 1-4C alkyl; M = metal cation with valency r; X1 = direct bond, 1-8C alkylene, 2-8C alkylene broken by O or S, -CH2CH(R8)- or gp. of formula (V); X2 = O or NH; X3 = 1-6C alkylene; X4 = O or NR11; X5 = direct bond, 1-8C alkylene, 2-6C alkenylene, =CH(R12) or gps. of formula (VI)-(VIII); X6 = 1-18C alkylene, 2-18C alkylene, 2-18C alkylene broken by O or S, or phenylene; m = 0-2; n = 1-6; p,q = 1 or 2; r = 1-3; when n = 1, then R3 = H, 1-25C alkyl, 5-12C cycloalkyl, Ph opt. substd. with 1-4C alkyl, or a monovalent residue of a hexose or hexitol, and if X2 = O, then R3 may = NH4 or Mr+/r; or, when n = 2, then R3 = 2-12C alkylene, 4-12C alkylene broken by O or S, or a divalent residue of a hexose or hexitol; or when n = 3, then R3 = -CH2-CH-CH2- or a trivalent residue of a hexose or hexitol; or when n = 4, then R3 = 4-10C alkane tetrayl or a tetravalent residue of a hexose or hexitol; or when n = 5, then R3 = a pentavalent residue of a hexose or a hexitol; or when n = 6, R3 = gp. (IX) or a hexavalent residue of a hexitol. The cpds. adhere well to the support and are not easily extracted by solvents, e.g. alcohols or hydrocarbons.
