Patent

CA 2425651

The invention provides a thermoplastic composition of C4-C7 isoolefin copolymers including halomethylstyrene units blended 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 elastomer which results in compositions having improved mechanical properties.

L'invention concerne une composition thermoplastique de copolymères d'iso-oléfine C¿4?-C¿7? comprenant des unités dérivées d'halométhylstyrène mélangées à un phosphine ou une amine entravée de la structure R¿1? R¿2? R¿3? N ou R¿1? R¿2? R¿3? P, dans laquelle R¿1?, R¿2? et R¿3? sont, de préférence, des groupes alkyles inférieurs ou supérieurs. On utilise les élastomères résultants modifiés par le phosphine ou l'amine, associés sur le plan ionique pour préparer des compositions de mélange d'élastomères thermoplastiques, notamment des compositions vulcanisées de manière dynamique renfermant des élastomères plus finement dispersés, ce qui débouche sur des compositions dotées de propriétés mécaniques supérieures.
