WIPO Patent Application WO/2004/052936
Kind Code:
A1
Abstract:
A natural rubber latex obtained by treating a natural rubber latex with an &agr - or ß-glucanase, e.g., an amylase or a cellulase, to decompose the glucans, which are polysaccharides, contained in the latex. Thus, the non-rubber ingredients in the natural rubber latex have been suitably treated enzymatically. Also provided are: a natural rubber which retains properties such as the effect of promoting the formation of extended crystals, antiaging effect, and vulcanization-accelerating effect, and is improved especially in wearing resistance and low-loss property; a process for producing the natural rubber; and a rubber composition containing the natural rubber and a tire obtained with the natural rubber.
