在浓硫酸催化下由丙烯酸或甲基丙烯酸与α,α,ω-三氢代全氟烷基醇直接酯化制得丙烯酸和甲基丙烯酸氟代烷基酯;探索了在过氧化苯甲酰或高氯酸硝酰存在下的聚合反应,得到了带羧基和羟基的粘性液体聚合物,可用全氟乙酸铬、氮丙啶及甲苯二异氰酸酯交联得到具有一定强度的弹性体,这类聚合物对强酸性强氧化剂如高氯酸硝酰和双-(N-三硝基乙基)硝氨乙烷等是化学稳定的。
Direct esterification of acrylic acid or methacrylic acid with α, α, ω-trihydroperfluoroalkyl alcohol catalyzed by concentrated sulfuric acid to produce fluoroalkyl acrylate and methacrylate; Or perchloric acid perchlorate to give a viscous liquid polymer having a carboxyl group and a hydroxyl group, which can be crosslinked with chromium perfluoroacetate, aziridine and tolylene diisocyanate to obtain an elastomer having a certain degree of strength. Such polymerization The material is chemically stable to strongly acidic strong oxidizing agents such as nitroxyl perchlorate and bis- (N-trinitroethyl) nitroethane.
