    摘要: Preparing brominated styrenic polymer by maintaining a mixture formed from (i) brominating agent, (ii) a solvent solution of styrenic polymer, and (iii) aluminum halide catalyst, at −20 to +20° C., and terminating bromination in 20 minutes or less. New brominated anionic styrenic polymers have better melt flow and/or lower initial ΔE values than the best previously-known brominated anionic styrenic polymers. Other features of such new polymers include high thermal stabilities at 320° C. and/or very low initial color values. Brominated styrenic polymers, especially brominated anionic styrenic polymers, are useful as flame retardants for thermoplastic polymers.

    摘要: A brominated styrenic polymer reaction mixture containing at least (i) brominated styrenic polymer, (ii) bromination reaction solvent, (iii) hydrogen bromide, and (iv) Lewis acid bromination catalyst, and an aqueous medium in an amount sufficient to deactivate the Lewis acid catalyst but insufficient to form a separate continuous liquid phase in the resultant mixture are mixed together to terminate bromination. The advantages of using such small amounts of aqueous medium, as well as various follow on procedures are described.

    摘要: Bromination of styrenic polymer is carried out in a closed reaction system to retain HX coproduct (where HX is HBr or HCl, or both) in the bromination reaction mixture at superatmospheric pressure. Preferably, the reaction mixture which includes the brominated styrenic polymer and substantially all of the HX coproduct formed is discharged into an aqueous quenching medium. By operating in this manner, the reaction is terminated and the brominated styrenic polymer of desired bromine content and substantially all HX coproduct are captured in the same operation, process equipment costs are reduced, and processing of the reaction mixture is facilitated.

    摘要: The present invention provides urethane oligomers of null,functional heterotelechelic polymers, and in particular heterotelechelic polyolefins having at least one terminal hydroxyl functionality and one other terminal functional group which is different from the hydroxyl functionality, such as an amine functional group. The oligomers of the invention can exhibit toughness, chemical resistance and other desired properties. The oligomers can also exhibit improved flexibility and impact resistance, due to the incorporation of the polyolefinic backbone. Thus the oligomers can be used in a variety of applications, including without limitation coatings, sealants, adhesives, and composites (prepregs). The heterotelechelic polyolefin is advantageously prepared via anionic polymerization using lithium initiators, and in particular functionalized lithium initiators having a protected hydroxy functionality as known in the art. The resulting living chain end can be functionalized using an amine functionalized electrophile, in which typically the amine group is protected. Alternatively amine protected functionalized initiators can used and the resulting living polymer functionalized using a hydroxy functionalizing electrophile. Protecting groups, when present, are removed to liberate the desired functionalities.
