摘要:
Provided herein are multimodal elastomer compositions comprising a first polymer fraction and a second polymer fraction, and methods for making such compositions. The elastomer compositions are preferably ethylene, α-olefin, copolymers or ethylene, α-olefin, polyene terpolymers. The elastomer compositions have high Mooney viscosity, thereby providing for improved elastomeric properties in compounds and other articles formed from the elastomer compositions. Surprisingly, the high Mooney viscosity compositions exhibit a much lower than expected viscosity when formulated into elastomer compounds. Thus, the processing detriments typically associated with high Mooney viscosity elastomers are minimized through the use of the elastomer compositions, and methods for making them, disclosed herein.
