The present invention provides a resin composition, pellets, briquettes, vibration-damping materials, sound-insulating materials, and interlayer films for laminated glass that have more excellent vibration-damping properties. The resin composition is specifically a resin composition containing the following block copolymer or its hydride (X) and a tackifying resin (Y) having a glass transition temperature of -50 to 45 ° C. When the glass transition temperature of the polymer block (B) of the hydride (X) is set to Tg (X), and when the glass transition temperature of the aforementioned tackifying resin (Y) is set to Tg (Y), Tg (X) and Tg ( The absolute value of the difference in Y) is 50 ° C or lower.n n n The block copolymer or its hydride (X) is a polymer block (A) having more than 70 mol% of structural units derived from an aromatic vinyl compound, and a polymer block (A) containing 30 mol% or more of A block copolymer of a polymer block (B) of a conjugated diene compound and at least one structural unit in the group of isobutylene, or a hydrogenated product thereof, wherein the polymer block (A ) Content is 25% by mass or less. |
