摘要:
A continuous process for the production of a dynamically vulcanized thermoplastic elastomer comprising a thermoplastic resin and a non-halogenated elastomer with a multiolefin content of greater than 3.5 mol% that has been modified in situ with a carboxylic anhydride. The process provides materials with improved elongation at break and ultimate tensile strength that can be produced economically and with reduced environmental impact.
摘要:
Rubber compounds containing a halobutyl elastomer, at least one additional elastomer, a mineral filler and at least a three component mixed modifier system comprising a silane compound, a phosphine compound and an additive containing at least one hydroxyl group and a functional group containing a basic amine. A process for preparing the compounds is also disclosed. The compounds are particularly useful in tire treads and exhibit improved processability, traction, rolling resistance and wear properties.
