    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.
