    摘要： An object of the present invention is to provide an additive composition that can impart excellent thermal resistance and flame retardancy to a synthetic resin. The additive composition contains a bromine-based flame retardant as a component (A), an antimony oxide as a component (B), a compound expressed by the formula (1) below as a component (C), and a phenolic antioxidant as a component (D).

    In the formula (1), R 1 , R 2 , R 3 , and R 4 each independently represent a hydrogen atom or a monovalent hydrocarbon group having 1 to 4 carbon atoms. It is preferable that R 1 , R 2 , R 3 , and R 4 in the formula (1) each independently represent a hydrogen atom or a linear alkyl group having 1 to 4 carbon atoms.

    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： An aryl composition includes aryl ether oligomers. These compositions may be prepared by reaction of one or more dihalobenzenes with one or more dihydroxybenzenes by an Ullman ether reaction. The oligomers may have two or more benzene rings and include terminal halogen, e.g., bromine (Br), or hydroxyl (OH) groups. These oligomers may be brominated to form flame retardant compositions for thermoplastic polymers.

    摘要： This invention provides a process of preparing reaction-derived decahalodiphenylethane of high purity. The process comprises cofeeding separate feeds of (a) diphenylethane and (b) bromine chloride, bromine chloride and bromine, or bromine chloride and chlorine to a refluxing reaction mixture comprising bromine and at least one Lewis acid bromination catalyst so that high purity decahalodiphenylethane is formed.
