The present invention relates to (halogenated) copolymer vulcanizates and the use thereof in devices such as seals, tank linings, o-rings or hoses which are in contact with liquid medium comprising oxymethylene ether.

Copolymer vulcanizates for use in contact with oxymethylene ether comprising media

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

The present invention relates to arborescent polymers and to a process for making same. In one embodiment, the present invention relates to arborescent polymers formed from at least one inimer and at least one isoolefin that have been end-functionalized with a polymer or copolymer having a low glass transition temperature (T), and to a process for making such arborescent polymers. In another embodiment, the present invention relates to arborescent polymers formed from at least one inimer and at least one isoolefin that have been end-functionalized with less than about 5 weight percent end blocks derived from a polymer or copolymer having a high glass transition temperature (T), and to a process for making such arborescent polymers.

Arborescent polymers and process for making same

The present invention relates to processes for recycling articles made from butyl ionomers and processes for producing recycled butyl ionomers. The invention further relates to composites comprising recycled butyl ionomers and fillers and articles made from recycled butyl ionomers. The invention also relates to uncured filled articles made from butyl ionomers having certain physical properties. Exemplary fillers include silica, carbon black, talc and clay, particularly onium substituted high aspect ratio nanoclays.

Recycled butyl ionomers and recycling processes

The present invention provides compositions containing halobutyl elastomers, at least one mineral filler and at least one oligomeric polyol compound or mixture of at least one oligomeric polyol compound and an additive which contains at least one hydroxyl group and at least one functional group having a basic amine group. The present invention also provides a process for preparing silica reinforced elastomer compounds with improved scorch safety including admixing halobutyl elastomers, at least one silica mineral filler and at least one oligomeric polyol compound or mixture of at least one oligomeric polyol compound and an additive which contains at least one hydroxyl group and at least one functional group having a basic amine group and curing the resulting filled halobutyl elastomer mixture.

Silica-filled elastomeric compounds

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.

Butyl rubber compounds comprising a three component mixed modifier system

A cationic polymerization process for isoolefins using a zinc halide initiator. The zinc halide initiator is added to a solution of the isoolefin in a suitable solvent, preferably a halocarbon solvent. Polymerization reactions are normally conducted at temperatures high enough to allow the zinc halide initiator to dissolve in the solution. An alkyl halide activator may optionally be used and is preferably added to the solution prior to the zinc halide initiator. A multiolefin may optionally be present in the solution. The process is particularly useful in the formation of isoolefin homopolymers and co-polymers of isoolefins and multiolefins, such as butyl rubber.

Polymerization process using zinc halide initiators

The present invention relates to silica-filled halogenated butyl elastomers, such as bromobutyl elastomers (BIIR). Further, the present invention also relates to bromobutyl elastomers with improved scorch safety.
