Abstract (en)
[origin: WO2011095540A2] The invention relates to a polymer foam having a density in the range between 5 and 120 kg/m3, containing a) a polymer component, containing at least one styrene polymer, b) 0.1 to 5 parts by weight (relative to 100 parts by weight of component a)) of a flame retardant mixture, containing b1) at least one phosphorus compound of formula (I) having a phosphorus content in the range between 5 and 80% by weight, relative to the phosphorus compound, (X1)s =PR1R2R3 (I), where the symbols and indices in formula (I) have the following meanings: R1 is C1-C16-alkyl, C1-C10-hydroxyalkyl, C2-C16-alkenyl, C1-C16-alkoxy, C2-C16-alkenoxy, C3-C10-cycloalkyl, C3-C10-cycloalkoxy, C6-C10-aryl, C6-C10-aryloxy, C6-C10-aryl-C1-C16-alkyl, C6-C10-aryl-C1-C16-alkoxy, SR9, COR10, COOR11, CONR12R13; R2 is C1-C16-alkyl, C1-C10-hydroxyalkyl, C2-C16-alkenyl, C1-C16-alkoxy, C2-C16-alkenoxy, C3-C10-cycloalkyl, C3-C10-cycloalkoxy, C6-C10-aryl, C6-C10-aryl-C1-C16-alkyl,C6-C10-aryl-C1-C16-alkoxy, SR9, COR10, COOR11, CONR12R13;R3 is H, SH, SR4, OH, OR5 or a group 30 -(Y1)n-[P(= X2)uR6 -(Y2)n]m-P(= X3)tR7R8; or two groups R1, R2, R3 together with the phosphorus atom to which they are bound form a ring system; X1, X2 and X3 are independently of each other identically or differently O or S; Y1, Y2 are identically or differently O or S; R4, R5, R9, R10, R11, R12,R13 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 or C6-C10-aryl C1-C4-alkyl; R6, R7, R8 are independently of each other identically or differently C1-C16-alkyl, C1-C16-alkenyl, C1-C16-alkoxy, C1-C16-alkenoxy, C3-C10-cycloalkyl, C3-C10-cycloalkoxy, C6-C10-aryl, C6-C10-aryloxy, C6-C10-aryl-C1-C16-alkyl, C6-C10-aryl-C1-C16-alkoxy, SR9, COR10, COOR11, CONR12R13; 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; m is a whole number between 0 and 100; s, t and u are independently of each other 0 or 1; and b2) elementary sulphur.
