PROBLEM TO BE SOLVED: To provide an interlayer for laminated glass, and laminated glass, which have excellent acoustic insulation over a wide range of temperature.SOLUTION: Provided is an interlayer for laminated glass comprising a thermoplastic elastomer layer as an internal layer 1 and adhesive layers as two outermost layers 2a and 2b, which when placed between two sheets of glass having a width of 50 mm, a length of 300 mm, and a thickness of 3 mm to obtain laminated glass and subjected to a damping test of the laminated glass by a center excitation method to measure a loss factor by a third mode, a width of temperature range where the loss factor becomes 0.2 or more is 15°C or more.SELECTED DRAWING: Figure 1 |
