Document Type and Number:
WIPO Patent Application WO/2018/212331
Kind Code:
A1
Abstract:
Provided is an intermediate film for laminated glass, which comprises a layer that uses a thermoplastic component other than a polyvinyl acetal resin, and which enables laminated glass that is provided with this intermediate film to have effectively enhanced sound insulation properties. An intermediate film for laminated glass according to the present invention has a structure of one layer or a structure of two or more layers, while comprising a thermoplastic elastomer layer that contains a thermoplastic elastomer and a plasticizer. This intermediate film for laminated glass is configured such that: the thermoplastic elastomer is an aliphatic polyolefin; the thermoplastic elastomer layer has a glass transition temperature within the temperature range of from -10°C to 10°C; and the maximum value of tan δ of the thermoplastic elastomer layer within the temperature range of from -10°C to 10°C is 1.5 or more.
