Abstract:
    The present invention relates to a deproteinizing agent for natural rubber latex, comprising a protease and one or more water-soluble polymers as an active component; a deproteinized natural rubber latex, which is prepared by subjecting to a deprotenization treatment using the deproteinizing agent, and a method of producing the same; a method of producing a rubber product, which comprises incorporating at least a vulcanizing agent into the latex, dipping a mold in the resulting compound latex, and vulcanizing and drying a rubber film formed on the mold; and a method of producing a rubber product, which comprises incorporating at least a heat sensitizer and a vulcanizing agent into the latex, dipping a mold in the resulting heat-sensitive coagulable compound latex, and vulcanizing and drying a rubber film formed on the mold.
