SILICONE POLYMER EMULSIONS |
摘要 |
Silicone oil-in-water emulsions containing a polysiloxane containing polymer is prepared by first preparing a polysiloxane containing polymer by the polymerisation of siloxane containing monomers and/or oligomers in the presence of an inert organopoly siloxane and/or an organic fluid, a suitable catalyst and optionally an end-blocking agent; and quenching the reaction if required. If required one or more surfactants may be introduced into the polysiloxane containing polymer to form a homogenous oil phase. Water is then added (in an amount of 0.1-10 percent by weight based on total oil phase weight) to the homogenous oil phase to form a water-in-oil emulsion. Shear is applied to the water-in-oil emulsion to cause inversion of the water-in-oil emulsion to an oil-in-water emulsion. Finally, if required the oil-in-water emulsion can be diluted by adding more water. |
