摘要： Preparation of butyl rubber based graft co-polymers from halobutyl elastomers using phase transfer catalysts in the presence of a solution of an alkali metal salt of an oxygen or sulfur nucleophile that is bound to a polymeric substrate. Graft co-polymers can be produced of a butyl polymer (isobutene-co-isoprene) and polymeric substrates such as polyethylene, polypropylene, polystyrene, polybutadiene, polysilanes, polysiloxanes, polyethylene glycol, polyethylene oxide, polyphosphazenes, polyferrocenes or their hybrids.

摘要： The present invention provides a process for preparing a filled halobutyl elastomer, which includes mixing a halobutyl elastomer with at least one mineral filler and at least one phosphine modifier and optionally curing the filled elastomer with sulfur or other curative systems. Filled halobutyl elastomers prepared according to the present invention possess improved levels of filler dispersion which results in a reduction in the hardness of the compound and an increased tensile strength.
