WIPO Patent Application WO/2017/135448

Kind Code:

A1

Abstract:

Provided is an interlayer for laminated glass with which the sound insulation of laminated glass at 30 °C can be increased. An interlayer for laminated glass according to the present invention is provided with first and second layers that include a thermoplastic resin and a plasticizer, wherein when the absolute value for the difference between the cloud points using the thermoplastic resins and plasticizers of the first and second layers is defined as Xa and the entire content of the plasticizer in the interlayer for laminated glass in terms of parts by weight relative to 100 parts by weight of the entire thermoplastic resin content of the interlayer for laminated glass is defined as Z, the interlayer satisfies a first configuration: "Xa ≤ 115 and Z ≤ -0.16Xa+59" and/or a second configuration: "when the thermoplastic resin in the first layer is a polyvinyl acetal resin and the degree of acetylation of the polyvinyl acetal resin in the first layer in terms of mol% is defined as Y, Y ≥ 2 and Z ≤ -0.16Xa-0.2Y+59".
