摘要

The rod-climbing experiment and its relationship to the first normal stress different of kaolinite particle-suspended polyisobutylene (PIB)/polybutene(PB) systems possessing Boger fluid characteristics (no shear-thinning and highly elastic) were investigated. The rod-climbing constants of the kaolinite/PIB/PB system obtained from the second-order fluid model increase with particle concentration and PIB molecular weight, indicating that the elasticity of the PIB/PB increases as kaolinite particle concentration increases. The first normal stress different obtained from the rod-climbing constant is also correlated with that measured value using RMS-800, a mechanical spectrometer, for the particle-suspended PIB/PB system.
