Aim at the dehydration rate of crude oil, the reaction conditions including water dosage, emulsifier dosage, initiator dosage, the rate of material inputting, polymerization temperature, monomer proportion, chain transfer agent dosage and terminator dosage were studied. The conditions of de-emulsification were studied too and using infrared spectrum ,the product was analyzed. The optimum condition and technology were shown as: water dosage was 60g, emulsifier dosage was 1.6g, initiator dosage was 0.25g, the time of add drop by drop was 120min, polymerization temperature was 80~85 , the total of monomer was
