<p>This method for producing a solid natural rubber involves: a radical-generating-agent addition step of adding a radical-generating agent to a natural rubber latex and advancing an oxidation reaction of cutting the molecular chains of the rubber; and a solidification step of drying and solidifying the natural rubber latex after the oxidation reaction and thereby obtaining a natural rubber that does not contain any aldehyde groups in the molecular chains thereof. The obtained solid natural rubber is reduced in molecular weight because the molecular chains have been cut, and does not contain any aldehyde groups in the molecular chains. Thus, the solid natural rubber is provided with a desired viscosity even without being masticated, and the viscosity thereof is less likely to increase during storage.</p> |
