摘要：
A composition is described, comprising: (a) from 20 to 80 wt % of a polyester; (b) from 5 to 35 wt % of a flame retardant phosphinate of the formula (I) [(R1)(R2)(PO)—O]−mMm+ (I), a flame retardant diphosphinate of the formula (II) [(O—POR1)(R3)(POR2—O)]2−nMxm+ (II), and/or a flame retardant polymer derived from the flame retardant phosphinate of the formula (I) or the flame retardant diphosphinate of the formula (II), wherein R1 and R2 are identical or different and are H, C1-C6-alkyl, linear or branched, or C6-C10-aryl; R3 is C1-C10-alkylene, linear or branched, C6-C10-arylene, -alkylarylene or -arylalkylene; M is an alkaline earth metal, alkali metal, Al, Ti, Zn, Fe, or boron; m is 1, 2, 3 or 4; n is 1, 2, or 3; and x is 1 or 2; (c) from 1 to 25 wt % of a melamine polyphosphate, melamine cyanurate, melamine pyrophosphate, and/or melamine phosphate; (d) from more than 0 to 25 wt % of a polyetherimide; and (e) optionally, an additive.
