Abstract: A process for producing a thermoplastic vulcanizate, the process comprising: (i) charging a reactor with an oil-extended olefinic copolymer rubber, where the rubber is synthesized by a single-site catalyst, characterized by a multi-modal molecular weight distribution, and includes greater than 10 parts by weight extender oil per 100 parts by weight rubber; (ii) charging the reactor, contemporaneously or sequentially with respect to the rubber, with a thermoplastic resin, an oil, and a cure system to provide a pre-vulcanized mixture; and (iii) mixing the rubber, thermoplastic resin, oil, and cure system at a temperature above the melt temperature of the thermoplastic resin to thereby cause dynamic vulcanization of the rubber and produce the thermoplastic vulcanizate.

Abstract: To obtain an elastomeric composite crumb having a majority of the particle size distribution greater than 0.33 cm, the crumb is obtained by a process whereby the elastomeric composite comprises less than about 0.5 phr of a salt of a C8 to C20 carboxylic acid, or 10 to 20 phr of a tackifying resin or a combination of both an absence of carboxylic acid and the presence of the tackifying resin. The use of one or both methods permits control of crumb particle size distribution in emulsion or solution processes for producing elastomeric nanocomposites. The elastomeric composite is also disclosed.

Abstract: This invention relates to an elastomeric nanocomposite composition, the composition comprising at least one elastomer, at least one nanofiller, and an ionomer stabilizer in the amount of at least about 0.5 phr of the composition, the elastomer comprising units derived from isoolefins having from 4 to 7 carbon atoms and at least one multiolefin, and the nanofiller consisting of a layered filler, wherein the stabilizer is added to improve the stability of the Mooney viscosity of the composition over time.
