The rod‐climbing experiment and its relationship to the first normal stress difference 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 increased 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 difference 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. © 2000 John Wiley & Sons, Inc.
