Zusammenfassung:	The present disclosure relates to compositions and elastomer cure processes. In at least one embodiment, a composition includes a phenol formaldehyde resin; a bisthiosulfate; and an elastomer comprising (1) a C4 to C7 isoolefin-derived monomer, a non-halogenated alkylstyrene momomer, and a halogenated alkylstyrene monomer, or (2) a C4 to C7 isoolefin-derived monomer and a halogenated diolefin. In at least one embodiment, a bromine-containing vulcanizate has a Mooney Viscosity (ML, 1+4 @ 100 °C) of 75 to 92; a cross-linking level (MH-ML) of 10 dNm to 19 dNm; a modulus at 300% of 3 MPa to 10 MPa; a aenergy at break of 3 J to 5 J.
