摘要

利用乳液聚合法合成了一种具有聚苯乙烯-聚丙烯酰胺核壳结构的微胶囊破壁剂。过硫酸铵作为破壁剂,聚苯乙烯作为外壳,聚丙烯酰胺作为载药剂。结果表明,合成的微胶囊凝胶破壁剂具有均匀的球形、优异的水分散性和更强的热稳定性。电导率测试表明,微胶囊的核壳结构有效地调节了作为破胶剂的过硫酸铵的释放,从而延迟了聚合物的破胶。

Preparation and Performance Evaluation of P(St-AM) Microencapsulated Gel-Breaking Agents with Core-Shell Structure

Utilizing emulsion polymerization, a microcapsule breaker with a polystyrene-polyacrylamide core-shell structure was synthesized. Ammonium persulfate served as the breaker, polystyrene as the shell, and polyacrylamide as the drug-carrying agent. The results demonstrated that the synthesized microencapsulated gel-breaker exhibited a uniform spherical shape, superior water dispersion, and enhanced thermal stability. Conductivity tests indicated that the core-shell structure of the microcapsules effectively regulated the release of ammonium persulfate as a gel-breaking agent, resulting in delayed polymer gel-breaking.

期刊介绍: Chemistry and Technology of Fuels and Oils publishes reports on improvements in the processing of petroleum and natural gas and cracking and refining techniques for the production of high-quality fuels, oils, greases, specialty fluids, additives and synthetics. The journal includes timely articles on the demulsification, desalting, and desulfurizing of crude oil; new flow plans for refineries; platforming, isomerization, catalytic reforming, and alkylation processes for obtaining aromatic hydrocarbons and high-octane gasoline; methods of producing ethylene, acetylene, benzene, acids, alcohols, esters, and other compounds from petroleum, as well as hydrogen from natural gas and liquid products.
