采用自由基水溶液共聚法制备了水溶性丙烯酸 -丙烯酰胺 -丙烯腈共聚物。对聚合反应温度、引发剂用量、尿素用量、聚合物浓度、电解质浓度、剪切速率、温度等因素对聚合物溶液性能的影响进行了研究。结果表明 ,合成的水溶性聚合物具有良好的增稠作用及耐温抗盐抗剪切等性能。
The water-soluble acrylic acid-acrylamide-acrylonitrile copolymer was prepared by radical copolymerization. The effects of polymerization temperature, initiator dosage, urea dosage, polymer concentration, electrolyte concentration, shear rate and temperature on the properties of polymer solution were studied. The results show that the synthetic water-soluble polymer has a good thickening effect and temperature and salt resistance to shear and other properties.
