Silicone Foam Control Agent |
摘要 |
A method of making silicone-based foam control agents comprising: i) preparing a polysiloxane containing polymer by the polymerisation of siloxane containing monomers and/or oligomers in the presence of an inert organopolysiloxane and/or an organic fluid, a suitable catalyst and optionally an end-blocking agent; ii) where required quenching the polymerisation process; wherein the inert organopolysiloxane and/or organic fluid is substantially retained within the resulting diluted polysiloxane containing polymer; iii) introducing from 0.1 to 10% by weight of a suitable filler prior to during or subsequent to step (i); iv) optionally introducing up to 5% by weight of a suitable silicone resin during or subsequent to step (i) and v) where required, adapting the foam control agent produced in steps (i) to (iv) into a suitable form of delivery therefor.
