There is provided a process and apparatus for the coagulation of an aqueous latex of a polymer wherein the latex and an aqueous coagulant are mixed in a tubular coagulation means which is disposed at an angle of from about 20.degree. up to 90.degree. to the horizontal plane and the coagulated mixture is passed from the tubular coagulation means to a conduit equipped with an impingement plate and then to means for separation, recovery and drying of the coagulated polymer.

Coagulation of latex

There is provided a process and apparatus for the coagulation of an aqueous latex of a polymer wherein the latex and an aqueous coagulant are mixed in a tubular coagulation means and the essentially completely coagulated mixture therefrom is passed into one or two vessels containing aqueous coagulant followed by separation, recovery and drying of the coagulated polymer.

Latex coagulation

A process is described for the production of particulate rubber wherein a synthetic rubber in latex form is coagulated to yield small particles and the particles are then coated with a rubbery-resinous or resinous polymer, the mixing conditions for each of the coagulation and coating being within certain limits of Reynolds Number and residence time. Such particulate rubber may be used for the manufacture of articles such as tire components or hoses and gaskets.
