The present invention has its object to provide a resin composition excellent in gas barrier properties, mechanical strength and elasticity and further showing only a slight extent of gravity deformation under high temperature conditions. The invention relates to a resin composition which comprises an isobutylene-based polymer (A), an isobutylene-based block copolymer (B) comprising a polymer block (b1) the constituent monomer(s) of which is(are) an aromatic vinyl compound(s) and a polymer block (b2) the constituent monomer(s) of which is(are) isobutylene, and a filler (C). This composition can be used as a sealant, in particular as a hot melt sealant for double glazing units, and as a hot melt spacer material for double glazing units. |
