Modified natural rubber particles, method for producing the same, and modified natural rubber latex

Provided are a modified natural rubber particle having a carbon double bond in a graft-copolymerized monomer on its surface, and a method for producing the same. The modified natural rubber particles are obtained by graft copolymerizing a natural rubber particle or a deproteinized natural rubber particle with a polyfunctional vinyl monomer having two or more carbon double bonds. It has a double bond of carbon in the polyfunctional vinyl monomer. One method for producing modified natural rubber particles is to react a polyfunctional vinyl monomer having two or more carbon double bonds with an inclusion protecting agent, so that at least one of the double bonds protects the inclusion. An inclusion protection complex synthesis step for synthesizing an inclusion protection complex protected by an agent, a grafting step of graft-copolymerizing the synthesized inclusion protection complex on natural rubber particles or deproteinized natural rubber particles, and A deprotection step of removing the inclusion protecting agent from the graft copolymer obtained.
