Rapid, homogeneous mixing of different liquids having substantially different viscosities from one another and inter-reactable rapidly upon contact to generate a gaseous reaction product, is accomplished by introducing the different liquids into a preliminary mixing chamber and effecting mutual contact and intermixing thereof under conditions of mild shear, then continuously moving the viscous liquid mixture into a closed main mixing chamber where it is subjected to conditions of severe shearing agitation, whilst maintaining the mixture under pressure conditions suitable to prevent substantial escape of the gaseous reaction product, followed by expulsion of the mixed liquid composition from the mixing chamber accompanied by release of pressure to permit release of gaseous reaction product, in a total time from mutual contact to expulsion from the chamber of not greater than 1 minute. |
