Silicone rubber matrices are used to contain and dispense volatile, organic liquids. The articles, as dispensors are improved by the use of silicone rubber matrices prepared by the curing of silicone fluids selected from the group consisting of polydiphenylsiloxane, polymethylphenylsiloxane, polymethyl-3,3,3-trifluoropropylsiloxane and a polydimethylsiloxane wherein 5% or more of the methyl groups of the polydimethylsiloxane are replaced by phenyl or polar aliphatic groups. Higher loadings of the organic liquid into the rubber matrix are achieved without syneresis occurring. |
