Document Type and Number:
Japanese Patent JP7316226
Kind Code:
B2
Abstract:
Provided is an interlayer film for laminated glass capable of enhancing the pour stability at the time of extrusion during production of the interlayer film for laminated glass, and having excellent shape stability. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer or two or more-layer structure, and includes a first layer containing a thermoplastic (meth)acrylic polymer and satisfies at least one of a first configuration that the thermoplastic (meth)acrylic polymer contained in the first layer is a thermoplastic (meth)acrylic polymer having a molecular weight distribution ratio of weight average molecular weight to number average molecular weight of 1 or more and 6 or less, and a second configuration that the thermoplastic (meth)acrylic polymer contained in the first layer is a thermoplastic (meth)acrylic polymer having a gel fraction of 5% by weight or less.
