    摘要: The present disclosure provides a rubber composition that can improve the steering stability and the wet performance of a tire while reducing the rolling resistance of the tire. The rubber composition includes a rubber component (A) including a natural rubber (A1) and a modified diene rubber (A2) having a glass transition temperature (Tg) of -50°C or lower, a thermoplastic resin (B), and a silica (C) such that the specific surface area by cetyltrimethylammonium bromide adsorption (CTAB) (m 2 /g) and the ink bottle-shaped micropore index (IB) satisfy IB ≤ -0.36 × CTAB + 86.8 (Expression Y). The amount of the thermoplastic resin (B) is 10 to 50 parts by mass per 100 parts by mass of the rubber component (A).

    摘要: [Technical Problem]
    There are provided a thermoplastic resin composition capable of bonding a cyclic polyolefin-based polymer and an ethylene-vinyl alcohol copolymer with sufficient strength and to provide a laminate using the same.
    [Solution of Problem]
    Thermoplastic resin composition comprising: (A) 100 parts by mass of a thermoplastic resin; (B) 0.05 to 5 parts by mass of one or more selected from the group consisting of an unsaturated carboxylic acid and a derivative of an unsaturated carboxylic acid; and (C) 0.01 to 3 parts by mass of an organic peroxide, said thermoplastic resin (A) comprising: (a1) 10 to 90 % by mass of a cyclic polyolefin-based polymer; and (a2) 90 to10 % by mass of one or more selected from the group consisting of a copolymer of an aromatic vinyl compound and a conjugated diene compound and a hydrogenated product thereof except for a hydrogenated product of a block copolymer of a polymer block mainly composed of an aromatic vinyl compound and a random copolymer block composed of a conjugated diene compound and an aromatic vinyl compound, wherein the total of the components (a1) and (a2) is 100 % by mass.
