Abstract: Rheological behaviour of polypropylene carbonate (PPC) has been studied.PPC isproved to be a pseudoplastic fluid.Its apparent viscosity decreases with increase of temperature,and the apparent activation energy decreases with increase of shearing rate as well.Quantitative relation between its viscosity and viscosity-average molecular weight is obtained.

Key words: polypropylene carbonate, rheological property, apparent viscosity, viscosity-aver-age molecular weight
