Abstract (en)
[origin: WO2011095552A1] The invention relates to phosphine sulfide derivatives of formula (I), S=PR1R2R3 (I) which are suitable as flame retardants, in particular for polymers, wherein the symbols in formula (I) have the following meanings: R1, R2 are identically or differently C1-C12-alkyl, C3-C8-cycloalkyl, which is unsubstituted or substituted by one or more C1-C4-alkyl groups, C2-C12-alkenyl, C2-C12-alkinyl, C6-C10-aryl, C6-C10-aryl-C1-C4-alkyl; R3 is H, SH, SR4, OH, OR5 or a group: -(Y1)n-[P(= X1)R6 -(Y2)n]m-P(= X2)R7R8; or two groups R1, R2, R3 together with the phosphorus atom to which they are bound form a ring system; X1, X2 are identically or differently O or S; Y1, Y2 are identically or differently O or S; R4, R5, R6, R7, R8 are independently of each other identically or differently C1-C12-alkyl, C3-C8-cycloalkyl, which is unsubstituted or substituted by one or more C1-C4-alkyl groups, C2-C12-alkenyl, C2-C12-alkinyl, C6-C10-aryl or C6-C10-aryl C1-C4-alkyl; n is 1 if Y1 or Y2 is O, and 1, 2, 3, 4, 5, 6, 7 or 8 if Y1 or Y2 is S, and m is a whole number between 0 and 100.
