Mixture comprises a synergistic mixture of (A) a compound or a mixture of two or more compounds of phosphonate compound, alkyl- or aryl-phosphonic acid, where the alkyl is 1-4C-alkyl and the aryl is optionally substituted benzyl, optionally substituted phenyl or optionally substituted naphthyl or a salt or ester of the above phosphonic acid; and (B) a 1,3,5-triazine compound or a mixture of two or more 1,3,5-triazine compound, e.g. tris-2-hydroxyethylisocyanurate or melamine pyrophosphate. Mixture comprises a synergistic mixture of (A) a compound or a mixture of two or more compounds of one or more phosphonate compound of formula (I) or (II), alkyl- or aryl-phosphonic acid, where the alkyl is 1-4C-alkyl and the aryl is optionally substituted benzyl, optionally substituted phenyl or optionally substituted naphthyl or a salt or ester of the above phosphonic acid; and (B) a 1,3,5-triazine compound or a mixture of two or more 1,3,5-triazine compound, preferably tris-2-hydroxyethylisocyanurate, poly-[2,4-(piperazin-1,4- yl)-6-(morpholin-4-yl)-1,3,5-triazine], dimelamine phosphate, melamine pyrophosphate or hindered amine compound of formula (R 1>NH-CH 2CH 2CH 2NR 2>CH 2CH 2NR 3>CH 2CH 2CH 2NHR 4>) (III), (T-E 1>-T 1>) (IV), (T-E 1>) (V) or (G-E 1>-G 1>-E 1>-G 2>) (VI). A 1>, A 2> : 1-4C-alkyl, benzyl, phenyl or naphthyl (all optionally substituted); A 3>, A 4> : CH 3 or C 2H 5; A 5> : 1-4C-alkyl, phenyl or benzyl (all optionally having up to 3 CH 3); R 1>, R 2> : s-triazine unit of formula (E); R 3>, R 4> : H or s-triazine unit (E), where one of R 3>, R 4> is s-triazine unit E and the other is H; R : CH 3, cyclohexyl or octyl; R 5> : 1-12C-alkyl; E 1> : triazine unit of formula (a); T, T 1> : a tetramine substituted with (II) (when R is cyclohexyl or octyl); L : propane-diyl, cyclohexane-diyl or octane-diyl; and G-G 2> : tetraamine subsisted with R 1>-R 4> of (III), with the exception that (E) in one of G and G 2> is replaced by E 1>, and two of (E) in G 1> is replaced by E 1>, so that there is a first bridge between G and G 1> and a second bridge between G 1> and G 2>. Where: one of the s-triazine unit (E) in each tetraamine is substituted by (E 1>), which forms a bridge between two tetraamine (T) and (T 1>), or E 1> exhibits same tetramine (T) at both ends and in (III) two of the E unit of the tetraamine are replaced by E 1>, or all three s-triazine substituent of the tetraamine (T) are E 1>. An independent claim is included for a process for introducing flame retardant characteristics to a polymer comprising adding the mixture. [Image] [Image] [Image] |
