SEALING MATERIAL FOR DOUBLE-GLAZING PANE COMPRISING RESIN COMPOSITION WITH EXCELLENT GAS-BARRIER PROPERTY AND HOT-MELT TACKINESS

摘要

A sealing material for double-glazing panes which eliminates the problem of the necessity of long-time aging after production and comprises a resin composition having high long-term adhesion strength, high shape retention, and high gas-barrier properties and especially having excellent hot-melt tackiness. The sealing material for double-glazing panes is characterized by comprising a resin composition which contains an isobutylene-based diblock copolymer (A) comprising a polymer block (a) derived from an aromatic vinyl compound as a constituent monomer and a polymer block (b) derived from isobutylene as a constituent monomer and which has hot-melt tackiness.
