Abstract

In a polysiloxane rubber composition which vulcanizes under heat to form an elastomer and comprising PA0 (a) a polyorganosiloxane containing unsaturated radicals, PA0 (b) a compound containing Si-H groups, PA0 (c) a platinum-containing addition catalyst, and PA0 (d) an organic peroxide, the improvement which comprises PA0 (e) a compound capable of forming a complex ligand with platinum, whereby the storability of the composition is improved.
