| Résumé : |
A cationic polyacrylate emulsion (CPAE) with a core-shell structure was prepared by seed polymerization. The emulsion copolymerization was carried out with the core monomoers of butyl acrylate (BA) and methyl methacrylate (MMA), the shell monomers of BA, MMA, and a home-made cationic monomer with the initiator potassium persulfate. The structure of CPAE was characterized. No 'C=C' double bond was detected in the structure of CPAE by FT-IR and 1H-NMR spectra, indicating that the polymerization reaction was complete. DSC curves showed that there were two glass transition temperature in the structure of CPAE, indicating that the emulsion particle featured a core-shell structure. The core-shell structure of CPAE was also confirmed by TEM observation. Many improvements to the coating properties emerged when CPAE was used as a leather finishing agent. The result leathers has uniform and clean grain and comfortable handle. The coating had strong adhesion and its resistance to wet and dry rub fastness was up to grade 4.5. |
