摘要
用毛细管流变仪研究了乙基纤维素（ＥＣ）及其高密度聚乙烯（ＨＤＰＥ）复合物，纤维素芳族酯（ＣＡＥ）及其聚碳酸酯（ＰＣ）复合物的剪切流变特性和机理。结果表明，ＥＣ对ＨＤＰＥ／ＥＣ复合物的粘度影响不大，而少量（５％）ＣＡＥ的加入使ＰＣ／ＣＡＥ复合物粘度大大下降，且复合物流变曲线呈现新的特征。
The rheological behavior and mechanism of ethyl cellulose (EC), HDPE/EC composite, cellulose aromatic ester (CAE) and PC/CAE composite were studied by capillary rheometer in this paper. The results show that the rheological cruves of HDPE/EC composite are similar to pure HDPE, but when a little CAE(5%) added η a of PC/CAE composite drop dramatically and the η a～ curves show so called three region flow which associated with CAE liquid crystalline orientation and better compatibility of CAE with PC.
