MODIFIED NATURAL RUBBER LATEX, MODIFIED NATURAL RUBBER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a modified natural rubber having excellent reinforcing properties and an affinity for carbon black and resultantly improving low loss properties and abrasion resistance of a rubber composition. SOLUTION: A modified natural rubber latex is obtained by adding a tin-containing monomer to a natural rubber latex and carrying out graft polymerization. The modified natural rubber is prepared from the modified natural rubber latex. A method for producing the modified natural rubber latex is characterized as adding the tin-containing monomer to the natural rubber latex and carrying out grafting of the monomer by emulsion polymerization. A rubber composition is obtained by compounding the modified natural rubber with carbon black. COPYRIGHT: (C)2005,JPO&NCIPI
