1. A method of manufacturing a synthetic elastomeric article comprising:
adding (i) a cross-linking composition comprising an aqueous solution of a negatively-charged multivalent metal complex ion having a pH of at least 9.0 and (ii) a second cross-linking agent comprising either: (a) sulphur and a sulphur donor, (b) a multivalent metal oxide or ionic cross-linking agent, (c) sulphur, a sulphur donor and an ionic cross-linking agent, or (d) sulphur donor, to an aqueous suspension of a synthetic carboxylated polymer having a pH of at least 9.0 to produce a synthetic latex composition, wherein a source of multivalent metal in the negatively charged multivalent metal complex ion is (A) a multimetal oxide of the multivalent metal, (B) a hydroxide of the multivalent metal, or (C) a salt of the multivalent metal;
shaping the synthetic latex composition; and
curing the synthetic latex composition so as to obtain the synthetic elastomeric article.
