Abstract: 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.

Abstract: 62-220,697 comb. PNEUMATIC TIRES A pneumatic tire having excellent tire performances in winter and summer seasons comprises a tread, a part of which is comprised of an expanded rubber in a volume corresponding to at least 10% of the total volume of the tread at its surface. This expanded rubber contains particular rubber component and particular high reinforcing carbon black and oil, and has particular number of closed cells having a specified cell diameter to the total number of closed cells. Furthermore, a rubber reinforcing layer is arranged near to the tread shoulder.

Abstract: A rubber composition containing a rubber-containing coagulum prepared from a natural rubber serum which was not utilized in the production of natural rubber according to the prior art and contains useful components such as anti-aging agent, which composition is reduced in the content of badly influential components causative of scorch and can exert the properties inherent in natural rubber at the maximum; and processes for producing the rubber-containing coagulums. The rubber composition is, for example, a composition which comprises a rubber component (A) consisting of at least one member selected from among natural rubber and diene-base synthetic rubbers and a rubber-containing coagulum component (B) obtained by subjecting a serum prepared by centrifuging a natural rubber latex to drying and coagulation.
