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.
Claims10
A thermoplastic vulcanizate comprising a polyamide and a low Mooney polymer selected from the group consisting of low Mooney, optionally hydrogenated nitrile terpolymers, low Mooney, optionally hydrogenated nitrile polymers or mixture thereof, wherein the low Mooney nitrile terpolymers and low Mooney nitrile polymers have a Mooney viscosity (ML(1+4) @ 100° C.) below 25, and wherein the low Mooney hydrogenated nitrile terpolymers and low Mooney hydrogenated nitrile polymers have a Mooney viscosity (ML(1+4) @ 100° C.) of between 1 and 55 and wherein the low Mooney hydrogenated nitrile terpolymers have a polydispersity of less than 2.5.
