Abstract: Provided is an interlayer film for laminated glass capable of enhancing the sound insulating property and the interlayer adhesive force in an interlayer film having increased transparency. 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, the interlayer film includes a first layer containing a vinyl monomer polymer, the vinyl monomer polymer is a polymer of a polymerizable composition containing a monomer having a functional group having hydrogen bondability, and a laminated glass in which the interlayer film for laminated glass is arranged between two sheets of float glass having a thickness of 2.0 mm, a length of 30 mm and a width of 2.5 cm in conformity with JIS R3202 has a haze, measured in conformity with JIS K6714 by using a haze meter, of 0.5% or less.

Abstract: Provided is an interlayer film for laminated glass capable of enhancing the interlayer adhesive force, and enhancing the sound insulating property after a lapse of a certain period of time from production of the interlayer film. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer or a two or more-layer structure, a compound obtained by trimethylsilylating the polyvinyl acetate in the presence of N,O-bis(trimethylsilyl)trifluoroacetamide shows a hydrogen peak of trimethylsilyl group existing at 0.06 ppm or more and 0.3 ppm or less in 1H-NMR measurement in chloroform-d, and a ratio of peak intensity of all peaks existing at 0.06 ppm or more and 0.3 ppm or less, to intensity of all peaks existing at 4.5 ppm or more and 5.3 ppm or less satisfies 0.02 or more and 3 or less.
