1-pentene/1-octene/1-dodecene terpolymer was synthesized by solvent polymerzation. The terpolymer was characterized by 13C NMR
FT-IR and XRD. The drag reduction efficiency of the terpolymer was evaluated by an indoor loop pipeline experimental apparatus. The Box-Behnken mathematical relational model between drag reduction rate and affecting factors was established
and the technology of preparing terpolymer was optimized. The optimum preparation conditions were: 0.07 ml 1-pentene
dodecene:octene=4
0.07 g main catalyst
0.4 ml cocatalyst
when the dosage of the terpolymer is 10×10-6
the drag reduction rate is 59.79%. The order of main factors affecting the drag reduction rate was: 1-pentene >cocatalyst >catalyst >dodecene:octene in the range of the experiment selected. The combined influence of the factors was also outstanding. The crystallinity of synthetic terpolymer was significantly decreased due to the introduction of 1-pentene
the solubleness was much better than 1-octene/1-dodecene bipolymer
