Partially crosslinked elastomeric polymers and process for producing the same

摘要

A partially crosslinked, unsaturated elastomeric polymer of a C4 to C7 isomonoolefin and a C4 to C14 conjugated multiolefin is provided which has a low crosslink density. The partially crosslinked polymer is produced by curing an uncrosslinked unsaturated polymer having a low level of chemically bound halogen with a curing agent which reacts only with the halogen. Processes for preparing these partially crosslinked unsaturated polymers are also provided.
