However, a disadvantage of using silanes is the progressive formation of alcohols during the manufacturing process and during use of articles made in this way.
In addition, the use of silanes can greatly increase the cost of the resulting manufactured article

Abstract
The present invention provides a process for preparing a filled halobutyl elastomer which comprises mixing a halobutyl elastomer, mineral filler and an oligomeric polyol compound or mixture of an oligomeric polyol compound and an additive containing at least one hydroxyl group and at least one functional group having a basic amine group, and curing the resulting filled elastomer mixture. The invention also relates to a filled elastomer composition prepared by said process having improved scorch safety.
Description
technical field [0001] The present invention relates to silica filled halobutyl elastomers such as brominated butyl elastomers (BIIR). Furthermore, the present invention relates to brominated butyl elastomers having improved scorch safety. Background technique [0002] It is known that reinforcing fillers such as carbon black and silica can greatly improve the strength and fatigue properties of elastomeric compounds. It is also known that there is a chemical interaction between the elastomer and the filler. For example, beneficial interactions between carbon black and highly unsaturated elastomers such as polybutadiene (BR), styrene butadiene copolymers (SBR) occur due to the presence of large amounts of carbon in these copolymers - carbon double bond. The carbon-carbon double bond in butyl elastomer may be only one-tenth or less than that of BR or SBR, so it is known that the compound made of butyl elastomer lacks good interaction with carbon black. For example, a compo...
