    摘要： The invention provides a method for increasing the viscosity of C4–C7 isoolefin copolymers including halomethylstyrene derived units by mixing the copolymer with a hindered amine or phosphine of the structure R1 R2 R3 N or R1 R2 R3 P wherein R1, R2 and R3 are preferably lower and higher alkyl groups. The resulting ionically associated, amino or phosphine modified elastomers are used to prepare thermoplastic elastomer blend compositions, including dynamically vulcanized compositions, containing more finely dispersed elastomers which results in compositions having improved mechanical properties.

    摘要： Oriented films are prepared. A thermoplastic vulcanizate, prepared by mixing at least 20 wt % of a thermoset rubber by weight of the total composition into a thermoplastic polymer are disclosed. After the mixture is prepared the thermoset rubber is entrained as discrete particles within the continuous thermoplastic polymer phase. The resulting composite is subjected to a stress either by pulling, blow molding, or any other film-forming process as is known in the art. This stress causes the continuous phase polymer molecules to become aligned or oriented in the direction in which the stress was applied, thus creating the oriented thermoplastic vulcanizate of the invention. This material has improved gas permeability and improved flexibility properties.

    摘要： The improved green strength, green elongation, and green relaxation properties of isobutylene-based elastomers at elevated temperatures along with improved aging and barrier properties are achieved by blending semi-compatible, semi-crystalline copolymers with the isobutylene elastomers. The semi-crystalline copolymers are typically copolymers of ethylene and an alpha-olefin having from 4 to 16 carbon atoms. The improved properties are maintained in subsequent rubber compounds containing said blends and are particularly useful in tire and pharmaceutical container applications.
