    摘要： N,N′-piperazinebis(neopentylglycol)phosphoramidate is used in combination with at least one co-additive which is (i) melamine, (ii) one or more melamine compounds or derivatives, or (iii) both of (i) and (ii) to provide effective flame retardancy in thermoplastic polymers. With polymers that tend to release trace amounts of acid under thermal processing conditions, a hydrotalcite is preferably included in the composition. In acid-sensitive polymers such as polyesters, the N,N′-piperazinebis(neopentylglycol)phosphoramidate should be free or essentially free of acid species as determinable by use of nmr, mass spec, and/or HPLC.

    摘要： A polyalkylene terephthalate polymer, such as polyethylene terephthalate, polybutylene terephthalate, blends or copolymers thereof, and analogous polyester-type engineering thermoplastics, with which has been blended a flame retardant amount of brominated styrenic polymer, such as brominated polystyrene, that, prior to blending, is characterized by (a) containing less than 700 ppm Cl and having a TGA temperature for 1% weight loss of 340° C. or higher; and/or (b) having an actual Mw which is within about 20%, and preferably within about 10%, of its calculated theoretical Mw, the theoretical Mw being based upon the actual bromine content of the brominated styrenic polymer and the Mw of the styrenic polymer reactant used to produce the brominated styrenic polymer; and/or (c) being essentially free of each of the following impurities: (1) ethylene dichloride, (2) bromodichloroethane, (3) dibromochloroethane, (4) dibromodichloroethane, and (5) tribrormochloroethane. These compositions most preferably also further comprise a reinforcing amount of glass fiber and/or a flame retardant synergist dispersed therein. It is now possible to provide polyalkylene terephthalate compositions that have a UL-94 rating of V-O using both {fraction (1/16)}-inch test specimens and {fraction (1/32)}-inch test specimens, and that have superior electrical resistance characteristics as reflected by a higher comparative tracking index and greater melt stability as determined by capillary rheometry.

    摘要： Thermally stable flame retardant additive compositions comprise a mixture of (1) a polybromodiphenylalkane and/or a polybromodiphenyl oxide, (2) a tetrabromobisphenol-A-bis(bromoalkyl ether), and preferably (3) a synthetic zeolite and/or hydrotalcite in specified proportions. Such additives are useful in thermoplastic polymers, such as homopolymers and copolymers of vinylaromatic monomers, and polyolefin polymers, especially impact or rubber-modified polystyrenes, and most especially HIPS.

Flame retardant polymer compositions comprising at least one thermoplastic polymer such as HIPS with which has been blended, singly and/or in one or more combinations, a flame retardant amount of at least (a), (b), and (c) have a very desirable balance of properties.
