    Abstract: A process for the synthesis of a granular polymer, the process comprising (a) providing an active polymerization mixture that includes polymer, monomer, catalyst and optional solvent; (b) introducing a hydroxy-containing diaryl acetyl compound to the active polymerization mixture to thereby provide an inactive polymer mixture; (c) separating the polymer solution into a first stream and a second stream, where the first stream includes the polymer and the hydroxy-containing diaryl acetyl compound, and the second stream includes the monomer and the optional solvent; and (d) fabricating granules from the first stream.

    Abstract: A flexible pipe for transporting fluids in hydrocarbon production. The flexible pipe includes at least one layer comprised of a thermoplastic vulcanizate (TPV) composition. In one embodiment, the TPV composition further includes a cyclic olefin copolymer present in a range from 0.1 wt % to 30 wt % based upon a total weight of the TPV composition. In another embodiment, the TPV composition further includes a hydrocarbon resin present in a range from 0.1 wt % to 30 wt % based upon a total weight of the TPV composition. In another embodiment, the TPV composition further includes a slip agent present in a range from 0.1 wt % to 30 wt % based upon a total weight of the TPV composition. In another embodiment, the TPV composition further includes a silicon hydride reducing agent compound with at least two Si—H groups. In another embodiment, the TPV composition further includes a polyolefin based compatibilizer. In another embodiment, the TPV composition has an abrasion resistance of 75 mg/1000 cycle or less. In another embodiment, the TPV composition has a CO2 gas permeability greater than 10 barrers.

    Abstract: Methods of post-polymerization modification of a polymer are provided herein. The present methods comprise the step of reacting a polymer with at least one nucleophile in a nucleophilic substitution reaction performed without a solvent to produce a functionalized polymer. The nucleophile can be selected from the group consisting of thioacetate, phenoxide, alkoxide, carboxylate, thiolate, thiocarboxylate, dithiocarboxylate, thiourea, thiocarbamate, dithiocarbamate, xanthate, thiocyanate. Nucleophilic substitution reaction can be performed in the presence of a phase transfer catalyst. Nucleophilic substitution reaction can also be performed via a two-step in-situ reactive mixing process with the initial formation of the polymer-amine ionomer (polymer-NR3+Br) which catalyzes the subsequent nucleophilic substitution with a second nucleophile to form a bi-functional polymer.
