ABSTRACT:
A process for producing high molecular weight polymers by the two-phase interfacial method comprising bringing two liquid phases containing polymerizable reactants continuously into contact with one another in a predetermined quantitative ratio to one another and passing the resulting mixture through one mixing stage or a plurality of serially connected mixing stages, the mixture being divided into a plurality of partial streams in each mixing stage, and causing the partial streams together with their flow boundaries to move transversely to their main directions of flow at mean speeds higher than 5 meters per second and to pass into a mixing chamber which has at least one outlet duct and in which the kinetic energy of the mixture is reduced from the highest value attained in the mixing to a value which is low in relation to said highest value, the portions of the mixture flowing in the mixing chamber being subjected to flow conditions which substantially vary at least periodically.
