摘要： An interlayer film for laminated glasses which prevents a decrease in TL value by lessening a coincidence effect and is highly effective in sound insulation in a wide temperature range. The interlayer film comprises: a polyacetal resin blend which comprises a polyacetal resin having an average degree of polymerization of 1,000 to 3,000 and a polyacetal resin having an average degree of polymerization of 3,000 to 5,000 and which has a degree of acetalization of 60 to 85 mol% and an acetyl group content of 8 to 30 mol%; and a plasticizer. The interlayer film, when examined for dynamic viscoelasticity, gives a temperature dependence of loss tangent in which the lowest-temperature side maximum of loss tangent appears at 30°C or lower.

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.摘要翻译： 本发明提供一种夹层玻璃用中间膜和夹层玻璃，通过所述重合效果的衰减来防止TL值的坍塌，并适合在宽的温度范围内显示出优异的隔音性能。 一种夹层玻璃用中间膜，其包含增塑剂和聚缩醛树脂，所述增塑剂和聚缩醛树脂是平均聚合度为1,000〜3,000的聚缩醛树脂和平均聚合度为3,000〜5,000的聚缩醛树脂的混合物， 缩醛化度为60〜85摩尔％，乙酰基含量为8〜30摩尔％。 在检查动态粘弹性时，显示在30℃以下出现损耗角正切的最低温度侧最大值的损耗角正切的温度依赖性的夹层玻璃用中间膜。
