| Abstract: | Styrene reacted with maleic anhydride under the initiator condition to prepare copolymer(SMA).Then,the copolymer reacted with mixed higher alcohols to gain the target product(SMAA).The optimal synthesis conditions of SMAA were studied by single factor and orthogonal experiment,and depression effect for high pour point crude from Liaoning Rita petroleum technology company was investigated.The results show that the best technological conditions of preparing SMA:molar ratio of maletic anhydride to styrene is 1... |
