Patent ID: 8067519

Claim:
A method of making a diluted chain extended organopolysiloxane containing polymer comprising the steps of: (a) reacting a pre-formed polymer with a chain extender reactable with terminal groups of the polymer, said chain extender being selected from the group of (i) a diacetamidosilane, a diacetoxysilane, a dichlorosilane, a diaminosilane where each amino group has one or two N—H bonds per nitrogen; a dialkoxysilane, a diamidosilane, a hexaorganodisilazane, and a diketoximinosilane; (vii) in the presence of a diluent material, a suitable catalyst and optionally an end-blocking agent; and (b) where required quenching the chain extension process; wherein the diluent material is substantially retained within the resulting diluted organopolysiloxane containing polymer and wherein the diluent material is selected from one or more of the group consisting of linear or branched mono unsaturated hydrocarbons; and mineral oil fractions comprising linear (n-paraffinic) mineral oils, branched (iso-paraffinic) mineral oils, cyclic (naphthenic) mineral oils, and mixtures thereof.
