自制反应性乳化剂制备的含氟核壳乳液及性能

采用烷基酚聚氧乙烯醚（OP-10）与顺丁烯二酸酐反应，制得反应性乳化剂；以甲基丙烯酸甲酯（MMA）和丙烯酸丁酯（BA）为核，甲基丙烯酸甲酯（MMA）、丙烯酸丁酯（BA）和甲基丙烯酸十二氟庚酯（DFMA）为壳，采用半连续种子乳液聚合方式制备核壳型含氟丙烯酸酯乳液。对反应性乳化剂的性能进行了初步探究，并通过红外光谱、TEM、DSC、CA、TGA等对体系进行了研究。结果表明，自制的反应性乳化剂性能优异，合成的乳胶粒具有典型的核壳结构，乳液性能稳定；反应性乳化剂的引入使涂层具有较低的表面能，有效地提高了乳胶膜的疏水性能。

Synthesis and properties of core-shell fluorinated acrylate copolymer with self-prepared reacative emulsifier

A reactive emulsifier was synthesized from alkylphenol ethoxylates （OP-10） and maleic anhydride. The synthesis and characterization of fluorinated acrylate copolymer with core-shell structure was carried out by emulsion polymerization in a mixed acrylate system including n-Butyl acrylate （BA）, methyl methacrylate （MMA） and dodecafluoroheptyl methacrylate （DFMA）. The emulsion and the films were characterized by Fourier trans- formed infrared （FT-IR） spectrometry, transmission electron microscopy （TEM）, differential scanning calorimetry （DSC） and contact angle （CA） analysis. The FT-IR spectra showed that monomers formed the fluorine-containing acrylate eopolymer. TEM and DCS characterizing results displayed that the copolymer presented a core-shell structure with a narrow particle size distribution. Moreover, the presence of the reactive emulsifier lowered the surface energy and improved the performance of the latex film.
