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。
Polyvinyl alcohol (PVA) modified by adding glycerol is investigated. The resuits show that glycerol has good plasticization effect on PVA. Glycerol decreases the melting point of PVA, and improves the elongations at break of PVA. Glycerol has not important influence on crystal phase, only important influence on noncrystal phase, according to wide angle X-ray diffraction analysis.
