Abstract
The invention provides a thermoplastic composition of C isoolefin copolymers including halomethylstyrene derived units blended with a hindered amine or phosphine of the structure R R R N or R R R P wherein R , R and R 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.
