Abstract

A method for the production of an extended and/or plasticised silicone rubber compositions comprising the steps:- Mixing a polysiloxane containing polymer and/or precursors thereof with: - an extender and/or plasticiser prior to and/or during polymerisation of the polysiloxane containing polymer and/or Filler during or subsequent to polymerisation of the polysiloxane containing polymer and and optionally introducing residual extender and/or plasticiser and/or filler together with a first cure package for curing the polymer subsequent to polymerisation characterised in that the extender and/or plasticiser is chemically functionalised so as to substantially not participate in any chemical reaction(s) with the polymer and/or its precursors, prior to cure, but is chemically attached to the cross-linked matrix of the resulting cured elastomer during curing.
