Research on Performance of the Monomers about Acrylic Pour Point Depressant

Kinds of pour point depressants were prepared from common monomers, octadecyl acrylate, maleic anhydride, styrene, acrylamide and vinyl acetate. Because the monomers have various functional groups, the performance of the polymers that were prepared from different monomers showed different. The performance of the pour point depressants on solubility in diesel and the drop of pour point on Daqing crude oil was studied. The results showed that styrene and vinyl acetate could increase the solubility of the pour point depressants; maleic anhydride and acrylamide could improve the drop of crude oil pour point; tercopolymer pour point depressants are more effective on the flow of crude oil than dimeric polymers, the highest drop of pour point was 14°C. Meanwhile, compostional pour point depressants are the best of them.
