Abstract
Highly oil-filled ethylene/alpha-olefin/diene (EAODM) polymers in a free flowing powder or pellet form, processes for preparing these polymers, and the use of these polymers to prepare thermoplastic vulcanizates (TPV) are provided. Thermoplastic vulcanizate premixes can be prepared with the EAODM polymers and thermoplastic polymers, the premixes being easily converted into TPVs.
