【Abstract】 Pour point depressants are very helpful to improve the low temperature flowing properties of diesel. Studying the influences of initiator concentration, temperature, pressure, and polymerization solvent on polymer structure, the idea of molecule design was applied in the synthesis of the pour point depressants, and different kinds of pour point depressants compounded in proper proportion is effective to improve the pour point depression and viscosity reduction.更多还原
