The emulsion polymerization of isoprene by cumene hydroperoxide Reynolds, Warren L.

Abstract

The emulsion polymerization of isoprene by means of cumene hydroperoxide was found to yield polymers of irreproducible intrinsic viscosities. The cause was found to be in the procedure used which was that recommended for drying GR-S type rubbers. The temperature and drying period finally found to be satisfactory were 35° C. and 48 hours. The formula recommended for the production of GR-S rubber by means of cumene hydroperoxide when applied to isoprene gave a rubber with too low a molecular weight. By studying the effect of varying the concentration of each of the components, and also the temperature, conditions have been established for the production of a satisfactory polymer.
