Abstract: 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.
