摘　　要：在聚合反应的后期阶段,向体系中引入含氟丙烯酸酯单体全氟辛基-(N-乙基-N-丙烯酸乙酯基)磺酰胺(QG-F814)共聚改性的方法制备了一种含氟丙烯酸树脂.接触角测定表明,该树脂具有良好的疏水性能.热重分析表明,该树脂在改性前后的耐热稳定性差别不大.A kind of fluoro-containing acrylic acid resin was prepared by adding a small amount of fluoro-containing monomer perfluoro-octane-( N-ethyl-N-ethyl acrylate) sulphamide (QG-F814) as modifying agent at the end of co-polymerization. Water contact angle determination shows that small amount of QG-F814 added into the system led to a high water repellence surface. TG/DTA analysis shows that the thermo stability of the modified resin is the same with the unmodified resin.
