Abstract
The present invention relates to thermoplastic vulcanizates (TPVs) based on low Mooney, optionally hydrogenated nitrile butadiene rubber and polyamides. The present invention also relates to TPVs based on low Mooney, optionally, hydrogenated nitrile terpolymers and polyamides. TPVs prepared according to the present invention have improved morphology, smaller rubber particle size, and improved processability compared to TPVs containing non-low Mooney, optionally hydrogenated nitrile butadiene rubber.
