摘要
本文测定了PC/PET共混物的表观粘度、剪切应力和熔体指数,讨论了共混温度和共混物组成对流变行为的影响。结果表明,共混物熔体为假塑性体,共混温度对流变行为影响不大。共混物的熔体粘度在PC/PET为75/25左右呈极小值。
In the present paper, the apparent viscosities and the shear stresses as well as the melt indexes of PC/PET blends prepared by melt blending were measured and the influnces of blending temperature and composition of blends on the theological behavior were discussed. It is found that the melts of blends are pseudoplastic fluid and the blending temperature effects on theological properties slightly. A minimum melt viscosity is observed at about PC/PET(75/25).
