Abstract: A composition comprises 99.99 to 95% by weight of a linear polyamide or polyurethane and 0.01 to 5% by weight of a compound having the general formula A-R1-B or E-R1-D where R1 is a divalent aliphatic radical with 2 to 12 carbon atoms or a divalent aromatic radical; A is E is R2 is hydroxy, methoxy, propoxy or butoxy or -O-CH2-O- or -O-CH2-CH2-O where the oxygen atoms are attached directly to adjacent positions of the benzene nucleus; R3 is hydrogen, methyl, ethyl, propyl, isobutyl, hydroxy, methoxy, ethoxy, propoxy or butoxy or -O-CH2-O- or -O-CH2-CH2-O-where the oxygen atoms are attached directly to adjacent positions of the benzene nucleus; B is hydrogen, A, COOR4 (where R4 is an alkyl group with one to eight carbon atoms), NHR5 (where R5 is an alkyl group with from one to four carbon atoms or an aryl group), N(R6)2 (where R6 is an alkyl group with one to four carbon atoms, an alkoxy group with one to carbon atoms or an aryloxy group with six to twelve carbon atoms) and D is hydrogen, E, COOR4, NHR5, NR6, an alkoxy group with 1 to 4 carbon atoms or an aryloxy group with six to twelve carbon atoms. Specified polyamides are polyhexamethylene adipamide, polym-xylylene adipamide, polypyrrolidone, polypiperidone, poly-e -caprolactam, poly-caprylic lactam, polydodecylic lactam and poly-undecylic lactam. Specified poly-urethanes are those derived from 1 : 6-hexane diisocyanate and 1 : 4-butylene diol. In the examples: (1) e -caprolactam and hexamethylene diammonium adipate are co-polymerized in the presence of 3 : 4-methylene dioxybenzal-p-amino-diphenylamine; (2) e -capolactam is polymerized in the presence of (a) N : N1 : bis - 3 : 4-methylene-dioxybenzal - ethylenediamine; (b) N : N1-bis - 3 : 4 - methylenedioxybenzal - p - phenylene diamine; (c) N-benzal-p-aminodiphenylamine; (d) N-4-oxy-3 : 5-ditertiarybutyl-benzal - p - aminodiphenylamine; (e) N - 4 - oxy - 3 - methoxybenzal - p - aminodiphenylamine; (f) N - benzal - b - naphthylamine; (g) N - 4 - oxy - 3 - methoxybenzal - b - naphthylamine; (h) N - 3 : 4 - methylenedioxybenzal - b - naphthylamine; (i) N : N1 - bis - 3 : 4 - methylenedioxybenzal - hexamethylenediamine; (j) N - 3 : 4 - methylenedioxybenzal - p - ethylaminobenzoate; (k) N - phenyl - N1 - 3 : 41 - methylenedioxybenzal - 1 : 4 - phenylenediamine, and (1) N-3 : 4-methylenedioxybenzal-aniline.

Abstract: A mixture stabilized against heat and light comprises 99.99 to 95% by weight of a linear polyamide, polyurethane or polyurea and 0.01 to 5% by weight of a bis-styryl benzene or a stilbene, each of which bears 1 to 5-OR radicals attached directly to the benzene nuclei, R being hydrogen, an alkyl group with 1 to 4 carbon atoms, a cycloalkyl group with 4 to 7 carbon atoms, an aralkyl group with 7 to 10 carbon atoms or -(CH2)n-owhere n is an integer from 1 to 4 and the oxygen atoms are attached in the o-position. Many polymers and stabilizers are specified. In the examples: (1), (2), (3), (7), (9) and (13) hexamethylene diammonium adipate and e -caprolactam are co-polymerized in the presence of:-(1) and (3) 3:4-methylene-dioxy-41-carbomethoxystilbene; (3) 3-methoxy-4-hydroxy-41-carbomethoxystilbene; (7) (a) 1:4-bis-(31:41-methylene dioxystyryl) benzene; (b) 1:3-bis(31:41-methylene dioxystyryl) benzene; (c) 1:4-bis(4-a -tetrahydrofuranyloxystyryl) benzene; (d) 1:4-bis(4-hydroxystyryl) benzene; (9) 1:4-bis(31:41\h -methylene dioxystyryl) benzene and (13) 1:2-bis-(3:41-methylene-dioxystyryl) benzene. In the remaining examples: (4)3:4-methylene dioxy-31-carbomethoxystilbene is mixed with polycaprylic lactam; (5) 3:4-methylene dioxy-31-carbomethoxystilbene is mixed with polyhexamethylene adipamide; (6) 3:4-methylene dioxy-31-carbomethoxystilbene is mixed with polyo -aminoundecanoic acid; (8) 1:4-bis(31:41-methylene dioxy-b -cyano-styryl) benzene is mixed with poly-e -caprolactam; (10) 1:4-bis-(31:41 -methylene-dioxystyryl) benzene is mixed with polycapryllic lactam; (11) 1:4-bis-(31:41-methylene dioxystyryl) benzene is mixed with polyhexamethylene adipamide and (12) 1:4-bis-(31:41-methylene dioxystyryl) benzene is mixed with polyo -aminoundecanoic acid.
