    摘要: The present invention provides a process for preparing a filled halobutyl elastomer, which includes mixing a halobutyl elastomer with at least one mineral filler and at least one phosphine modifier and optionally curing the filled elastomer with sulfur or other curative systems. Filled halobutyl elastomers prepared according to the present invention possess improved levels of filler dispersion which results in a reduction in the hardness of the compound and an increased tensile strength.

    摘要: A process for preparing a functionalised polyolefin is described. The process comprises the step of reacting: (i) a polyolefin, (ii) a compound containing a functional group, and (iii) a coagent compound having Formula I: Xn—Y—Zm  (I) wherein: Y is a core moiety; Z is a moiety containing a carbon-carbon double bond or a carbon-carbon triple bond; X is a moiety different than Z and the bond between X and Y may be a single bond or a double bond; n is a whole number greater than or equal to 0; m is a whole number greater than or equal to 2; and m+n equals a number up to the valence of Y; wherein: (a) when m is 2 and n is 0, the process comprises initially reacting the polyolefin and the coagent to form a product that is then reacted with the compound containing the functional group, and (b) the compound containing a functional group is substantially inert in free radical-mediated polymerization reactions and in free radical-mediated grafting reactions. The invention also relates to a functionalized polyolefin produced by such a process. The polyolefins, particularly high molecular weight polyolefins (Mn>10,000), can be extensively modified with functional groups (e.g., thiols, epoxides, anhydrides, carboxylic acids, amines, amides, boron-containing compounds, silicon-containing compounds, cyano-containing compounds, sulfates, sulfonates, sulfites, esters, thioesters, dithioesters, ether, halides, phosphates, phosphonates, phosphines, phosphites and other compounds containing polar moieties) without altering molecular weight thereby rendering the functionalised polyolefins useful in a wide range of applications.

    摘要: Disclosed are propylene-based polymers with improved melt strength, improved strain hardening characteristics and processes for producing the same. The processes include reacting a polyamine with a maleic anhydride-grafted-propylene-based polymer. The processes produce a rheology-modified propylene-based polymer with long chain branching by forming a polyimide linkage which couples polymer chains of the propylene-based polymer. The polyimide-coupled propylene-based polymer exhibits improved melt strength and improved strain hardening characteristics.
