Abstract:
1. A method for the fabrication of a polyisoprene or polynitrile aqueous emulsion useful in the manufacture of, gloves and related products, wherein the aqueous emulsion is a stable polyisoprene aqueous emulsion or polynitrile aqueous emulsion obtained through free-radical emulsion polymerization initiated by an initiating agent under normal pressure of isoprene as the monomer, or of a 50-94 wt % isoprene monomer, 5˜42 wt % acrylonitrile monomer, and 1-8 wt % (methyl) acrylic acid as a monomer mixture, with an emulsifying agent and dispersing agent as an emulsification system, and an oxidation-reduction initiating system, characterized in that: after said isoprene or mixture of isoprene monomer, acrylonitrile monomer, and (methyl) acrylic acid is mixed with the initiating agent, and an oil phase obtained, the oil phase together with a reducing agent in the oxidation-reduction initiating system, is added dropwise in different time quantums.
