ABSTRACT OF THE DISCLOSURE This invention relates to compositions comprising an elastomeric material based on a styrene-butadiene-alkyl (meth) acrylate copolymer also including an ethylenically unsaturated carboxylic acid. The compositions are used for forming a sealing gasket for a container that contains an organic solvent, by crosslinking with a polyvalent metal crosslinking agent, and preferably also a vulcanizing crosslinking agent. The preferred ethylenically unsaturated carboxylic acid is itaconic acid.
