    • Phosphine sulfide derivatives of the formula (I), S═PR1R2R3  (I) are suitable as flame retardants, in particular for polymers, where the definitions of the symbols in the formula (I) are as follows: R1 and R2 are identical or different, being C1-C12-alkyl, C3-C8-cycloalkyl, which may have no substitution or may have one or more C1-C4-alkyl groups as substituents, C2-C12-alkenyl, C2-C12-alkynyl, C6-C10-aryl, or C8-C10-aryl-C1-C4-alkyl; R3 is H, SH, SR4, OH, OR5 or a —(Y1)n—[P(═X1)R6—(Y2)n]m—P(═X2)R7R8 group; or two groups R1, R2, R3 form, together with the phosphorus atom bonded thereto, a ring system; X1 and X2 are identical or different, being O or S; Y1 and Y2 are identical or different, being O or S; R4, R5, R6, R7 and R8 are identical or different, being independently from one another C1-C12-alkyl, C3-C8-cycloalkyl, which may have no substitution or may have one or more C1-C4-alkyl groups as substituents, C2-C12-alkenyl, C2-C12-alkynyl, C6-C10-aryl, or C6-C10-aryl-C1-C4-alkyl; n is 1 if Y1 and, respectively, Y2 is O, and is 1, 2, 3, 4, 5, 6, 7, or 8 if Y1 and, respectively, Y2 is S, and m is an integer from 0 to 100.
    • 式(I)的硫化膦衍生物,S = PR1R2R3(I)适用作阻燃剂,特别是用于聚合物的阻燃剂,其中式(I)中符号的定义如下:R1和R2相同或不同 可以不具有取代基或可以具有一个或多个C 1 -C 4烷基作为取代基的C 1 -C 12 - 烷基,C 3 -C 8 - 环烷基,C 2 -C 12 - 烯基,C 2 -C 12炔基,C 6 -C 10 - 芳基或C 8 -C 10 - 芳基-C 1 -C 4 - 烷基; R3是H,SH,SR4,OH,OR5或 - (Y1)n- [P(= X1)R6-(Y2)n] m-P(= X2)R7R8组; 或两个基团R 1,R 2,R 3与键合的磷原子一起形成环系; X1和X2相同或不同,为O或S; Y1和Y2相同或不同,为O或S; R 4,R 5,R 6,R 7和R 8相同或不同,彼此独立地为可以不具有取代基或可以具有一个或多个C 1 -C 4 - 烷基作为取代基的C 1 -C 12 - 烷基,C 3 -C 8 - 环烷基 ,C 2 -C 12 - 烯基,C 2 -C 12 - 炔基,C 6 -C 10 - 芳基或C 6 -C 10 - 芳基-C 1 -C 4 - 烷基; 如果Y1和Y1分别为0,则n为1,如果Y1分别为Y2,并且分别为1,2,3,4,5,6,7或8,并且m分别为0至100的整数。 。
