<p>A process is provided for preparing thiofunctional polysiloxane polymers. The process includes reacting a cyclic trisiloxane with a silicon compound, which is either a specifically recited silane or a particular recited organosiloxane, in the presence of an acid catalyst having a pH value below 1.0, in which at least one of the above cyclic trisiloxane or silicon compounds contains at least one thiol group. These triofunctional polysiloxane polymers are useful as metal protectants and as release agents, especially on metal substrates.</p> |
