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