【Abstract】 The functions of solvents polarity on the procedure of palygorskite modified by 2-bromoisobutyral bromide were investigated through rheological measuring.The experimental results showed that the action style between palygorskite and 2-bromoisobutyral bromide depended on the polarity of the solvents.In solvents with more polarity such as propylene oxide and epoxexane,the efficiency of the palygorskite clay modified by 2-bromoisobutyral bromide was better than that in solvents with less polarity such as 1-octane.更多还原
