Abstract
The present invention provides a process for preparing a filled halobutyl elastomer, which includes mixing a halobutyl elastomer, particles of filler an additive containing both amino and alcohol functional groups, and one or more hydrated metal halogens and optional curing the filled elastomer with sulfur or other curative systems. The compositions of the present invention have improved properties when compared to known carbon black-filled halobutyl elastomeric compositions combined with an enhanced scorch safety. This present invention has the advantages of (a) not evolving alcohol either during the manufacture or subsequent use of the article manufactured from the compound, and (b) maintaining good processability of the compound.
