Abstract
The invention provides a method for increasing the viscosity of C–Cisoolefin copolymers including halomethylstyrene derived units by mixing the copolymer with a hindered amine or phosphine of the structure RRRN or RRRP wherein R, Rand Rare 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.
