The invention provides an interlayer film for a laminated glass and a laminated glass, which are protected against a slump in TL value through attenuation of said coincidence effect and adapted to display an outstanding sound insulation performance over a broad temperature range. An interlayer film for a laminated glass comprising a plasticizer and a polyacetal resin, which is a blend of a polyacetal resin having an average polymerization degree of 1, 000 to 3, 000 and a polyacetal resin having an average polymerization degree of 3, 000 to 5, 000, and which has an acetalization degree of 60 to 85 mol % and an acetyl group content of 8 to 30 mol %. An interlayer film for a laminated glass which shows a temperature dependence of loss tangent in which the lowest-temperature side maximum of loss tangent appears at 30°C or lower when examined for dynamic viscoelasticity.

L'invention procure une pellicule intercouche destinée au verre feuilleté ainsi qu'un verre feuilleté, dont les feuillets sont protégés contre l'affaissement en indice d'affaiblissement acoustique grâce à l'atténuation de l'effet de coïncidence et conçus pour assurer une insonorisation remarquable sur une vaste gamme de températures. La pellicule intercouche pour le verre feuilleté est constituée d'un plastifiant et d'une résine polyacétalique, laquelle est un mélange de résine polyacétalique possédant un degré moyen de polymérisation entre 1 000 et 3 000 et d'une résine polyacétalique possédant un degré moyen de polymérisation entre 3 000 et 5 000, avec un degré d'acétalisation de 60 à 85 % en moles, et une teneur en groupement acétal de 8 à 30 % en moles. Pellicule intercouche pour verre feuilleté dont le facteur de dissipation varie en fonction de la température, la plus faible température à laquelle cet effet se manifeste est de 30 degrés Celsius, du point de vue de la viscoéleasticité dynamique.
