NATURAL RUBBER PRODUCED FROM LATEX AND COMPOSITION COMPRISING THE SAME

摘要

Provided is a natural rubber obtained by drying a gathered natural rubber latex without coagulating, wherein a drum dryer and/or a conveyor type dryer are used for drying. Further, provided are a production process for a natural rubber-filler mixture prepared by adding at least one of carbon black and inorganic fillers to a natural rubber latex, a natural rubber added a viscosity stabilizer comprising hydrazide compounds or esters of aromatic or aliphatic polycarboxylic acid derivatives to these natural rubber and natural rubber-filler mixture, and a rubber composition which is prepared using the above natural rubbers and which is excellent in productivity, abrasion resistance and fracture resistance.
