A resin composition which is excellent in gas-barrier properties, mechanical strength, and elasticity and has low self-weight deformability even under high-temperature conditions. The resin composition comprises an isobutylene polymer (A), an isobutylene block copolymer (B) comprising a polymer block (b1) obtained from an aromatic vinyl compound as a constituent monomer and a polymer block (b2) obtained from isobutylene as a constituent monomer, and a filler (C). This composition is usable as a sealing material, in particular, a hot-melt sealing material for double glazings, and a hot-melt spacer for double glazings. |
