摘要： The natural rubber of the present invention is natural rubber obtained by leaving standing for a prescribed period of time a hydrous coagulum obtained from a natural rubber latex to which a preservative is added and/or from a coagulum of a natural rubber latex to which a preservative is added and drying it. The natural rubber coagulum is inhibited from being changed in a molecular weight even in a standing step (aging) in a high moisture condition, whereby the natural rubber having stable mechanical properties is obtained. An isothiazoline base compound is used for the preservative. Further, a rubber composition containing the natural rubber is prepared, and a tire is produced by using the rubber composition.

摘要： A method of transporting semi-processed rubber comprises locating the semi-processed rubber in a ship and supplying heat to the semi-processed rubber during transit to prevent solidification of, and/or crystallisation in, the semi-processed rubber. Heat may be re-circulated from the ship's engine to heat the hold in which the rubber is stored. Insulating material may be provided to insulate the walls of the ship's hold.

摘要： A process for producing a chlorinated rubber which comprises chlorinating a latex or aqueous dispersion of a rubber to prepare a chlorinated rubber cake which weakly to highly acidic, drying the cake by fluidized drying together with a drying medium, and successively drying the resultant predried powder by fluidized drying. Thus, a high-quality chlorinated rubber can be efficiently obtained from the chlorinated rubber cake while attaining satisfactory handleability.
