研究了甲基丙烯酸2，2，2-三氟乙酯（TFEMA）、甲基丙烯酸1，1，1，3，3，3-六氟异丙酯（HFIPMA）、丙烯酸2，2，2-三氟乙酯（TFEA）和甲基丙烯酸1，1，1，3，3-六氟异丙酯（HFIPMA）的动力学聚合行为。采用等温差示扫描量热法（DSC）和高效液相色谱法（HPLC）测定了丙烯酸-3-六氟异丙酯（HFIPA）的含量以改善氟化粉末-液体粘合剂树脂的性能。计算了转化率和聚合热，并考察了均聚物在常用溶剂中的溶解度。与MMA相比，过氧化苯甲酰（BPO）引发的聚合反应速率依次为TFEA>MMA>TFEMA>HFIPA>HFIPMA。基于通过HPLC测定的单体的保留时间，发现单体的疏水性按MMA<TFEA<TFEMA<HFIPA<HFIPMA的顺序增加。综合研究结果表明，TFEA和HFIPA是氟化粉末-液体粘合剂树脂的单体液体组分的潜在候选者。
The kinetic polymerization behavior of 2,2,2-trifluoroethyl methacrylate (TFEMA), 1,1,1,3,3,3-hexafluoroisopropyl methacrylate (HFIPMA), 2,2,2-trifluoroethyl acrylate (TFEA) and 1,1,1,3,3,3-hexafluoroisopropyl acrylate (HFIPA) was determined by isothermal differential scanning calorimetry (DSC) and high-performance liquid chromatography (HPLC) in order to improve the properties of fluorinated powder-liquid adhesive resins. Conversion and heat of polymerization were calculated, and the solubility of the homopolymers in common solvents was examined. Comparison of their polymerization reactivity with that of MMA revealed that the overall rate of polymerization initiated by benzoyl peroxide (BPO) decreased in the order TFEA>MMA>TFEMA>HFIPA>HFIPMA. Based on the retention time of the monomer determined by HPLC, the hydrophobicity of the monomers was found to increase in the order MMA<TFEA<TFEMA<HFIPA<HFIPMA. The overall research results suggested that TFEA and HFIPA would be potentially promising candidates for the monomer liquid component of fluorinated powder-liquid adhesive resins.
