| Abstract: | The paper studied the reaction of the active hydroxyl of molecular chain in hydroxypropyl guar gum(HPG) with 1-bromo dodecane molecule for the preparation of hydrophobically modified hydroxypropyl guar gum(BD-HAHPG) through the introduction of long-chain hydrophobic monomers to hydrophilic hydroxypropyl guar gum molecular chain.The optimum conditions of synthesis have been obtained as follows:reaction temperature 80℃,the concentration of active agent 2.0%, the concentration of HPG 9.0%,the concentration of 1-bromo dodecane 1.7%,and the reaction time 6 h.The results of rheological property showed that BD-HAHPG had viscosity increasing,thermal-resistance, salt-tolerance and shear resistance properties. |
