Abstract
Oilfield elements and assemblies are described comprising, in one embodiment, an elastomeric composition comprising the reaction product of a linear or branched polymer having residual ethylenic unsaturation with an ethylenically unsaturated organic monomer having at least one reactive moiety selected from acid, acid anhydride, and acid salt, the elastomeric composition formed into an oilfield element. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims.
