    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 present invention is a method of cutting an imaging element. An imaging element is moved through a cutting zone formed by a first cutting blade having a first cutting surface and a first engaging surface and a second cutting blade having a second cutting surface and a second engaging surface. In the cutting zone the first engaging surface and the second engaging surface are in contact for a distance greater than or equal to a thickness of the imaging element. The first cutting surface and said second cutting surface are separated by from 1 to 30 percent of the thickness of the imaging element in the cutting zone. The present invention reduces debris and skiving generation.
