MODIFIED LATEX, AND PRODUCT CONTAINING HYDROGENATED NATURAL POLYISOPRENOID OR ITS MODIFICATION

摘要

PROBLEM TO BE SOLVED: To provide a modified latex producible from a natural polyisoprenoid latex as raw material and useful for obtaining a product having high heat resistance and weatherability. SOLUTION: The modified latex obtained by hydrogenating a natural polyisoprenoid latex is provided. The modified latex includes one obtained by reacting a natural polyisoprenoid latex with hydrogen in the presence of a hydrogenation catalyst. It is preferable that the hydrogenation percentage of the hydrogenated natural polyisoprenoid in the modified latex be 50% or greater. The natural polyisoprenoid latex to be used is one derived from Hevea rubber tree, India rubber tree, Eucommia ulmoides or Lactarius mushroom. COPYRIGHT: (C)2006,JPO&NCIPI
