三氟氯乙烯-醋酸乙烯酯-叔碳酸乙烯酯含氟乳液的合成
Study of Chlorotrifluoroethylene-Vinylacetate-Vinyl Ester of Versatic Acid Containing Fluorine Emulsion
摘要
Abstract
The emulsion copolymerization of chJorotrifluoroethylene (CTFE) , vinyl acetate (Vac), vinyl ester of versaticacid(VeoValO) was carried out, forming a serious of stable emulsions with 33% solid in mass fraction and particles in size 105-205 nm. Fourier transform infrared spectroscopy of the copolymers were investigated and a transmission electron microscope was used to observe the shape of latex particles. The influences of emulsifier CF3(CF2)6 COONH, dosage, initiator KJSjOsdosage and the reaction temperature on the latex particle size and size distribution were discussed. The influences of different monomer ratio on minimum filming temperature of emulsion and glass transition temperature of polymer film were also studied. The results show that increasing CF3(CF2)6 COONHidosage, K^SA* dosage and reaction temperature make the size of latex particles small. Increasing CFj(CF2)6 COONH. Dosage, KjSjO, dosage make the number of latex particles large. Along with the increase of VeoValO dosage, minimum filming temperature of emulsion and glass transition temperature of polymer film become lower.关键词
