中文摘要 | 本研究發現適當的聚乙烯醇與丙三醇之添加於糊化澱粉後的混煉產品,可形成不同柔軟度、吸水性與水溶性之樣品,其中丙三醇可促進成分間相與相之互溶性而形成高柔軟性的產物,但是此種混煉物之熱加工性亦受限於其熱分解點。 |
英文摘要 | In this studies the gelatinized starch was compounded with poly(vinyl alcohol) of varying molecular weight and hydrophilic groups and also with different quantities of glycerol. The compounded polymer shown different properties of softness, water adsorption and water solubility index. The presence of glycerol promote the phase solubility between different polymer chain and increase the softness of polymer compounds. The processibility of such starch compounded polymer will be limited by their thermal degradability during high temperature processing. |
