摘要
本文研究了聚丙撑碳酸酯的流动性能及其影响因素，实验表明聚丙撑碳酸酯为假塑性流体，它的表观粘度随着温度升高而降低，流动活化能随着剪切速率增加而变小，并得到了表观粘度与粘均分子量之间的定量关系．
Rheological behaviour of polypropylene carbonate (PPC)and its effective factors arestudied. PPC is proved pseudoplastic fluid. Its apparent viscosity decreases withincreasing of temperature, apparent activation energy decreasing with increasing of shearingrate. Quantitative relation between its viscosity and viscosity-average molecular weightis obtained.
