    摘要: An elastomeric copolymer of an aromatic vinyl compound and butadiene prepared by a solution polymerization method, which has a glass transition temperature of not less than -50.degree. C. and contains polymer chains modified with a trifunctional or tetrafunctional coupling agent, and which contains not less than 3% by weight to less than 23% by weight, based on the whole polymer chains, of polymer chains having a molecular weight of at least 5 times a molecular weight corresponding to a peak appearing on the low molecular weight side of a high performance liquid chromatogram of the elastomeric copolymer. The elastomeric copolymer has an excellent processability and shows a low rolling resistance and a high wet grip characteristic when used as a rubber component in tires.

    摘要: A spawning case for use in an aquarium comprises in combination a rectangular case body (A) and filter (B). The case body (A) is arranged within the aquarium so as to communicate with water. The case body A includes a multiplicity of passage slits (11) and a W-shaped partition member (20) having communication paths (24) formed at its valleys. The filter (B) is removably mounted on the external surface of the case body (A). The filter (B) includes on its one side an intake (C) which is brought into intimate contact with the passage slits (11), and at its upper portion a discharge port (33) capable of being selectively directed toward either the interior or the exterior of the case body (A).
