摘要：
A polymer foam with density in the range from 5 to 120 kg/m3, comprising a) a polymer component, comprising at least one styrene polymer, b) from 0.1 to 5 parts by weight (based on 100 parts by weight of component a)) of a flame retardant mixture, comprising b1) at least one phosphorus compound of the formula (I) having phosphorus content in the range from 5 to 80% by weight, based on the phosphorus compound, (X1)s═PR1R2R3 (I) where the definitions of the symbols and indices in the formula (I) are as follows: R1 is C1-C16-alkyl, C1-C10-hydroxyalkyl, 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; R2 is C1-C16-alkyl, C1-C10-hydroxyalkyl, C1-C16-alkenyl, C1-C16-alkoxy, C1-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 —(Y1)n—[P(═X2)uR6—(Y2)n]m—P(═X3)tR7R8 group; or two groups R1, R2, R3 form, together with the phosphorus atom bonded thereto, a ring system; X1, X2 and X3 are identical or different and, independently of one another, O or S; Y1 and Y2 are identical or different, being O or S; R4, R5, R9, R10, R11, R12, and R13 are identical or different, being C1-C12-alkyl, C3-C8-cycloalkyl, which may either have no substitution or may have one or more C1-C4-alkyl groups as substituents, or being C2-C12-alkenyl, C2-C12-alkynyl, C6-C10-aryl, or C6-C10-aryl-C1-C4-alkyl; R6, R7, and R8 are identical or different and, independently of one another, 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 and, respectively, Y2 is O, and is 1, 2, 3, 4, 5, 6, 7, or 8 if Y1 and, respectively, Y2 is S; m is an integer from 0 to 100; s, t, and u are, independently of one another, 0 or 1; and b2) elemental sulfur.
