A polymeric film composition, which can readily be applied to a sheet-configured substrate and which resists creep at room temperature, even when the sheet/film combination is stored as a roll, is disclosed.
The polymeric film composition has a viscosity of at least 3×10
6
Pa-s at a predetermined first lower temperature and at a shear stress of 10,000 Pa and a viscosity no greater than 1×10
4
Pa-s at a predetermined second higher temperature and at a shear stress of 50,000 Pa.
本发明公开了一种聚合薄膜组合物,它可以很容易地涂敷在片状基底上,即使片状/薄膜组合物以卷筒形式存放,在室温下也能抵抗蠕变。
这种聚合物薄膜组合物的粘度至少为 3×10
6
Pa-s,并且在剪切应力为 10,000 Pa 时粘度不大于 1×10.4
4
Pa-s。
