答案

This paper dicusses condiditions such as using tetradecyl acrylic acid and vinyl acetate as the raw material and toluene as the solvent,and oxi-reduction (BPO) as the initiator to synthesize the acrylic ester diesel pour inhibitor.The quantity of different solvents,initiator,ratio of monomers,reaction temperature,reaction time are examined to observe the impact of molecular weight distribution generated by a series of multipolymer like tetradecyl acrylic acid and vinyl acetate copolymer PAVA on the reduce of low-freezing of Daqing-20 # diesel .
