Abstract
The rheological properties of KGM/WG blending system were studied. The results showed that the viscosity of KGM/WG compound system decreased with the increase of shear rate,exhibiting a typical pseudoplastic. KGM/WG compound system was highly concentration–dependent as the higher concentration led to more obvious increase in viscosity. Compared with the pure KGM,the rheological properties and thermal stability of the compound system was obvious improved with adding a certain amount of WG. The sample KW8 had stronger intermolecular forces and the best rheological properties.
