Abstract: Provided is a polymer that contributes to the improvement of the durability and weather resistance of rubber compositions or rubber products such as a tire, and has low crystallinity. Disclosed is a multicomponent copolymer comprising a conjugated diene unit, a non-conjugated olefin unit, and an aromatic vinyl unit, wherein the multicomponent copolymer has a main chain consisting only of an acyclic structure, and the content of cis-1,4 bonds in the entire conjugated diene unit is 50% or more.

Abstract: There is provided a transmission apparatus including: a buffer provided with a queue for each of user flows, the buffer configured to store data in the queue for the user flow to which the data belongs; a storage unit configured to store a link list indicating an output order of the user flows; an issuing unit configured to issue a predetermined output permissible amount to the queue for the user flow by referring to the link list; and an output control unit configured to output data from the queue to which the output permissible amount is issued.

Abstract: A multiblock copolymer, obtainable by copolymerization of a conjugated diene compound and a non-conjugated olefin, wherein: a structure of the multiblock copolymer includes A-(B-A)x and/or B-(A-B)x, wherein “A” represents a block portion constituted of monomer units of a non-conjugated olefin, “B” represents a block portion constituted of monomer units of a conjugated diene compound, and “x” represents an integer ?1; content of the non-conjugated olefin portion is ?30 mass %; and storage modulus G? at 130° C., measured by rubber process analysis using a rubber process analyzer, i.e. RPA, according to ASTM D6204, is ?20 kPa. It is possible to obtain vulcanized rubber and thus a tire having high fracture resistance and high weather resistance from the multiblock copolymer and a rubber composition derived therefrom.
