This invention relates to the method for fabrication of polyisoprene aqueous emulsion, gloves and related products thereof, wherein the aqueous emulsion is polyisoprene or polynitrile aqueous emulsion obtained through free-radical emulsion polymerization initiated by initiating agent under normal pressure with isoprene as the monomer, or isoprene monomer, acrylonitrile monomer, and (methyl)acrylic acid as the monomer mixture, and emulsifying agent and dispersing agent as the emulsification system. After the isoprene or the mixture of isoprene monomer, acrylonitrile monomer, and (methyl)acrylic acid is mixed with the initiating agent, the oil phase obtained together with reducing agent is added dropwise in different time quantums. The polymerization conversion rate of polyisoprene aqueous emulsion or polynitrile aqueous emulsion according to this invention is increased from the original 78% to over 97.5%. Fabricated polyisoprene or polynitrile gloves and thin latex products thereof have high strength and good extensibility, provide good hand touch, and do not cause allergies of the human body. They can be used for various purposes.
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:
