| 摘 要： | 在聚乙烯醇(PVA)中加入增塑剂甘油对其进行改性,结果表明,甘油对PVA有很强的增塑作用,降低了其熔点,提高了其断裂伸长率,并由X射线衍射仪表征得知,甘油主要影响PVA的非晶区,在晶区中对其晶型没有很大的影响。

| Abstract: | Polyvinyl alcohol (PVA) modified by adding glycerol is investigated.The re- sults show that glycerol has good plasticization effect on PVA.Glycerol decreases the melt- ing point of PVA,and improves the elongations at break of PVA.Glycerol has not impor- tant influence on crystal phase,only important influence on noncrystal phase,according to wide angle X-ray diffraction analysis. |

| Keywords: | polyvinyl alcohol films modification plasticization glycerol |
