发明名称 TREATED LATEX OF NATURAL RUBBER, ITS NATURAL RUBBER AND RUBBER COMPOSITION AND TIRE USING THE SAME
摘要 PROBLEM TO BE SOLVED: To provide a natural rubber latex subjected to a suitable enzymic treatment for a nonrubber component in aspects of rubber characteristics and to provide natural rubber, sufficiently maintaining physical properties such as developing/promoting effects on stretch crystallinity, antiaging effects or vulcanization promoting effects and having excellent abrasion resistance, a method for producing the natural rubber and the rubber compsition and a tire using the natural rubber. SOLUTION: The natural rubber latex is obtained by degrading a plant tissue and subjected to the enzymic treatment with especially a cellulase. The natural rubber is prepared from the natural rubber latex. The tire is used by vulcanizing a composition using the natural rubber. COPYRIGHT: (C)2004,JPO&NCIPI
