ABSTRACT:
An ultra high molecular weight polymer emulsion is produced by emulsion polymerization of a vinyl monomer, wherein the oxygen concentration in the aqueous phase of the reaction system is maintained at a smaller percentage by weight than the percentage by weight of the dissolved oxygen concentration in a 0.5 wt % sodium bisulfite aqueous solution. An emulsifier and a redox polymerization initiator are used for the emulsion polymerization.
