專利摘要(中)
本發明係提供一種聚乙烯醇膜，係一種經熱處理改質的聚乙烯醇膜，其經泡水2分鐘後之熱重量分析曲線中，具有一增塑劑之裂解訊號；且該聚乙烯醇膜於未經熱處理改質前，其經泡水2分鐘後之熱重量分析曲線中，不具有該增塑劑之裂解訊號。本發明之經熱處理改質的聚乙烯醇膜，可增加該聚乙烯醇膜的耐水能力，可使增塑劑在遇到水分子時，更好地被保存於該聚乙烯醇膜內。

專利摘要(英)
The present invention provides a polyvinyl alcohol film, which is a polyvinyl alcohol film modified by heat treatment. The thermogravimetric analysis curve after soaking in water for 2 minutes has a cracking signal of a plasticizer; before the polyvinyl alcohol film was not modified by heat treatment, the thermogravimetric analysis curve after soaking in water for 2 minutes did not have the cracking signal of the plasticizer. The polyvinyl alcohol film modified by heat treatment of the present invention can increase the water resistance of the polyvinyl alcohol film, so that plasticizer can be better preserved in the polyvinyl alcohol film when it encounters water molecules.
