Abstract:
A process for producing a reaction mixture without a stirring apparatus comprising the steps of:a) feeding at least two low viscosity components and a high viscosity polyol to a mixing zone, wherein said high viscosity polyol has a viscosity of at least 3000 mPa.s;b) mixing said at least two low viscosity components and said high viscosity polyol in the mixing zone, wherein one of said at least two low viscosity components is an isocyanate; said high viscosity polyol is fed into the mixing zone at a low pressure and said at least two low viscosity components are injected at high pressure into the stream of said high viscosity polyolwherein the cross-sectional area of said high viscosity polyol stream is 10 to 100 times greater than the sum of the cross-sectional areas of said at least two low viscosity components.
