ABSTRACT:
The invention relates to a process for preparing thiofunctional polysiloxane polymers which comprises reacting a disiloxane and/or a hydroxy or hydrocarbonoxy containing silane or siloxane with a cyclic trisiloxane in the presence of an acid catalyst wherein at least one of the above organosilicon compounds contain a thiol group. These thiofunctional polysiloxane polymers are useful as metal protectants and as release agents, especially on metal substrates.
