    摘要: Thermoplastic, flame-resistant copolymers comprised of an alkenyl aromatic compound, a bromine-substituted alkenyl aromatic compound, an .alpha.,.beta.-unsaturated monocarboxylic acid and a diene rubber are described. The copolymers are prepared by polymerizing the comonomers in solution. The copolymers are admixable with other materials, both polymeric and non-polymeric, and the resulting compositions can be molded into articles of various shapes and sizes which exhibit improved paint adhesion.

    摘要: Functionalized polyphenylene ether compositions are provided which are particularly useful for effecting compatibility for a blend of polyphenylene ether resin and a polyamide resin. The functionalized-polyphenylene ether is the reaction product of a polyphenylene ether polymer and a compound having the general formula (i)--Z--(ii), wherein group (i) is a polyphenylene ether-philic moiety such as acyl chloride, group (ii) is a polyamide-philic moiety such as dicarboxylic acid anhydride, and Z is a divalent hydrocarbon radical providing a covalent linkage between groups (i) and (ii). An example of the compound having general formula (i)--Z--(ii) is trimellitic anhydride acid chloride.

    摘要: Flame retardant poly(alkenyl aromatic) oligomers and lower molecular weight polymers having bromine substituents on the aromatic nucleus are prepared by cationic polymerization from the corresponding brominated monomers, for example, bromostyrene, in an organic solvent, using a Lewis acid catalyst and an aromatic chain transfer agent. The lower molecular weights enable greater tolerance with other thermoplastic polymers, and as a result compatible flame retardant blends with good ductile impact properties are possible.
