GLASS LAMINATE, AND METHOD FOR USING BLOCK COPOLYMER HYDROGENATION PRODUCT AS BINDER FOR GLASS LAMINATE |
摘要 |
A laminated glass may be obtained by integrally bonding glass sheets through an adhesive, the adhesive comprising a hydrogenated block copolymer obtained by introducing an alkoxysilyl group into a hydrogenated block copolymer that is obtained by hydrogenating unsaturated bonds of a block copolymer that comprises at least two polymer blocks and at least one polymer block, the polymer block comprising a repeating unit derived from an aromatic vinyl compound as a main component, the polymer block comprising a repeating unit derived from a linear conjugated diene compound as a main component, and a ratio (wA:wB) of a weight fraction wA of the polymer block in the block copolymer to a weight fraction wB of the polymer block in the block copolymer being 30:70 to 60:40. The laminated glass may employ a block copolymer hydrogenation product comprising an alkoxysilyl group and excellent light-fastness, heat resistance, moisture resistance and transparency. |

1. Laminated glass obtained by integrally bonding glass sheets through an adhesive, the adhesive comprising a hydrogenated block copolymer obtained by introducing an alkoxysilyl group into a hydrogenated block copolymer that is obtained by hydrogenating 90% or more of unsaturated bonds of a block copolymer that comprises at least two polymer blocks and at least one polymer block, the polymer block comprising a repeating unit derived from an aromatic vinyl compound as a main component, the polymer block comprising a repeating unit derived from a linear conjugated diene compound as a main component, and a ratio (wA:wB) of a weight fraction wA of the polymer block in the block copolymer to a weight fraction wB of the polymer block in the block copolymer being 30:70 to 60:40. |
