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.

Process for continuous production of halogen-free thermoplastic elastomer compositions

The present invention is directed to a method for preparing isobutene from a renewable source and their use in the preparation of renewable polymers. The invention also discloses purification of isobutene, selective removal of 1-butene, cis-2-butene and trans-2-butene using microporous adsorbent material, and the oligomerization of the purified liquid isobutene yielding diisobutenes and triisobutenes.

Polymers of isobutene from renewable sources

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.
