Multistage process for the manufacture of peroxide cured hxnbr-polyamide thermoplastic vulcanizates
摘要
<p>The present invention relates to a multistage process including at least two steps for making a heat and oil resistant preroxide-cured thermoplastic vulcanizates (TPV) based on hydrogenated carboxlated nitrile butadiene rubber (HXNBR) and at least one polyamide. TPV's according to the present invention have improved properties and morphology over known TPV's prepared in single-stage processes.</p>
