MODIFIED NATURAL RUBBER PARTICLE, PROCESS FOR PRODUCING THE MODIFIED NATURAL RUBBER PARTICLE, AND MODIFIED NATURAL RUBBER LATEX |
摘要 |
The present invention provides a modified natural rubber particle having the carbon-carbon double bonds assigned to monomers graft-copolymerized onto the surface of the modified natural rubber particle, and a production method thereof. A modified natural rubber particle having carbon-carbon double bonds assigned to multifunctional vinyl monomers graft-copolymerized onto the surface of the modified natural rubber particle, which is prepared by graft-copolymerization of multifunctional vinyl monomers having two or more carbon-carbon double bonds onto natural rubber particles or deproteinized natural rubber particles. One of the methods for producing a modified natural rubber particle includes the steps of: forming inclusion complex of the multifunctional vinyl monomers having two or more carbon-carbon double bonds with a guest-protecting agent to protect at least one of the double bonds of the multifunctional vinyl monomers; graft-copolymerizing the resulting inclusion complex onto natural rubber particles or deproteinized natural rubber particles; and deprotecting the protected double bonds by removing the guest-protecting agent from the obtained graft-copolymer. |
