Abstract:
The influence of glycerin on static rheological properties and the rehological behaviors of SPI solutions were investigated. The change of shear viscosity of SPI with concentration and temperature after adding glycerin was discussed, specially comparing with SPI control solution. The results have indicated that SPI/glycerin solutions presented a typical behavior of pseudoplastic fluid, and glycerin not only reduced the viscosity and weakened pseudoplastic behavior of SPI but also improve its thermal stability.
