    • The present invention relates to a proton exchange membrane having a polymer comprising of a main chain and a branch chain connected to said main chain wherein the chemical formula for said branch chain is and where n is an integer. Said main chain is a polymer selected from the group that includes: aliphatic polymers, aliphatic block polymers, and aliphatic random copolymers. The fabrication method for said polymers comprises the steps of: reacting a polymer having a benzene ring in its branch chain with a sulfo-alkylated chemical reagent and a catalyst in an anhydrous solvent in an inert atmosphere; separating the resulting sulfo-alkylated polymer; and acidifying to obtain said fabricated polymer. Proton exchange membranes made with these polymers are pliant, do not expand much during wet conditions, and, are chemically, hydrolytically, dimensionally and thermally stable.

    • 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.
