Abstract
Official abstract text for this publication.
The present invention is a laminated glass which is prepared by inserting a resin intermediate film between glass plates and adhering the glass plates to integrate them, having a bending deflection at 90° C. is 7.3 N/mm 2 or higher, a weight per unit area is 7.5 kg/m 2 or less, wherein the resin intermediate film contains a modified hydrogenated block copolymer [E] obtained by introducing an alkoxysilyl group into a hydrogenated block copolymer [D], storage elastic moduli in the dynamic viscoelastic properties of the resin intermediate film are 5×10 8 Pa or lower at a temperature of −20° C. and 2×10 7 Pa or higher at a temperature of 90° C., and the hydrogenated block copolymer [D] is obtained by hydrogenating 90% or more of carbon-carbon unsaturated bonds on a main chain and side chains and carbon-carbon unsaturated bonds on an aromatic ring in a specific block copolymer [C].

1 . A laminated glass which is prepared by inserting a resin intermediate film between glass plates and adhering the glass plates to integrate them, having a bending deflection at 90° C. is 7.3 N/mm 2 or higher, a weight per unit area is 7.5 kg/m 2 or less, wherein the resin intermediate film contains a modified hydrogenated block copolymer [E] obtained by introducing an alkoxysilyl group into a hydrogenated block copolymer [D], storage elastic moduli in the dynamic viscoelastic properties of the resin intermediate film are 5×10 8 Pa or lower at a temperature of −20° C. and 2×10 7 Pa or higher at a temperature of 90° C., and the hydrogenated block copolymer [D] is obtained by hydrogenating 90% or more of carbon-carbon unsaturated bonds on a main chain and side chains and carbon-carbon unsaturated bonds on an aromatic ring in a block copolymer [C] which is containing at least two polymer blocks [A] mainly containing a structural unit derived from an aromatic vinyl compound and at least one polymer block [B] mainly containing a structural unit derived from an acyclic conjugated diene compound.
