摘要： PROBLEM TO BE SOLVED: To provide a vulcanizable ethylenic copolymer rubber composition (pellets) which comprises an ethylene-α-olefin-nonconjugated polyene copolymer rubber (A) and a polyolefin resin (B), contains the polyolefin resin (B) in a micro dispersed state, and does not block. SOLUTION: This method for producing the rubber composition is characterized by feeding a rubber mixture (E) comprising 100 pts. wt. of the ethylene-α-olefin-nonconjugated polyene copolymer rubber (A) and 3 to 10 pts. wt. of an organic solvent (D) from a supply portion of a multistage vent-having extruder into the extruder, and also feeding the polyolefin resin (B) from another supply portion into the extruder in an atmosphere of an inert gas, thereby kneading the rubber mixture (E) with the polyolefin resin (B) and removing the solvent.

摘要： PROBLEM TO BE SOLVED: To obtain a desired bale-shaped rubber composition surely by using a specified material and doing extrusion, cutting, and compression continuously under set conditions. SOLUTION: A kind of ethylene-α-olefin-nonconjugated polyene copolymer rubber prepared from ethylene, a 3-20C α-olefin, and a nonconjugated polyene and a material of a polyolefin resin are used. With the use of an extruder 2, polyethylene is mixed with EPT, and the temperature of cooling water in transportation water, the diameter of a die, the thickness of pellets, the temperature of the pellets at compression molding, and others are set up at respective conditions to enable the large-scale production of good bales. For example, when the temperature of cooling water in transportation in a transportation route 30, which has been approximately 40 deg.C usually, is increased to 90-100 deg.C, the temperature of the bale can be increased to nearly 100 deg.C to be solidified roughly as a bale.
