Document Type and Number:
WIPO Patent Application WO/2019/151327
Kind Code:
A1
Abstract:
Provided is an intermediate film which is for laminated glass and can improve sound insulation over a wide temperature range of 0-40°C. This intermediate film for laminated glass has a monolayer or multilayer structure, and comprises a resin layer. In a viscoelastic measurement of the intermediate film carried out at a frequency of 1 Hz in shear mode, the ratio of a first storage modulus G' at a peak temperature of the maximum peak of tanδ to a second storage modulus G' at a temperature of 100°C higher than the peak temperature of the maximum peak of tanδ is 50-500.
