    摘要： A halogenated phenyl ether flame retardant is described having the general formula (I): wherein each X is independently C1 or Br, n is an integer of from 0 to 12, and each p is independently an integer of 1 to 4, provided that, when each X is C1, the total amount halogen in the ether is from about 50 to about 65 wt% and when each X is Br, the total amount halogen in the ether is from at least 70 wt % to about 79 wt% and wherein from about 30% to about 80%, for example from about 35% to about 75% of the halogenated ethers are fully halogenated the remainder being partially halogenated. In many embodiments, mixtures of compounds of formula I with different values of n are present. The present flame retardant provides superior mechanical properties when incorporated into a polymer than similar flame retardants which contain a higher amount of fully halogenated species.

    摘要： A flame-retardant resin composition comprises a base resin (A), such as a polyester, polyamide or polycarbonate resin, and an organophosphorus compound (B) having at least one of the following formulas (I), (II) and (III): where A is selected from O, S, SO
    2 , a single bond, alkyl, and -CH
    2 - P
    1 ; - P
    1 is a phosphorus -containing group of the formula: R
    1 and R
    2 are the same or different and each is selected from H, O-alkyl, O-aryl, alkyl, aryl, and OM; R
    3 is H or alkyl; M = Na, K, Zn, Al, Ca; a is an integer from O to 4, provided that a is at least 1 unit for each polymer chain; n is an integer from 1 to 100,000 and m is an integer from 0 to 100,000.
