Abstract:
In order to introduce a new redox surface initiating systemon the feather surface, mercaptoacetic acid was used to reduce the disulfide bond in the disulfide bond in the feather into mercapto groups and potassium persulfate (KPS) disolved on the solution constitute a new redox surface initiating system, the graft-polymerization of glycidyl methacrylate (GMA) in the aqueous solvent was realized to obtaining the grafted polymer Feather-g-PGMA. The modified feather were characterized by FT-IR, SEM and TGA. The effects of monomer concentration, initiator concentration and temperature on the feather grafting were discussed. Experimental results show that the -SH/ KPS can smoothly initiate the graft-polymerization of GMA on the surface of feather in a aqueous solvent, the optimum conditions of graft-modified feather that monomer concentration is 0.55mol/L, initiator concentration is 2.6mmol/L and temperature is 40℃. The grafting rate of Feather-g-PGMA is up to 185.8% and the thermal stability of feather grafted PGMA is decreased.
Key words: feather, redox initiation system, glycidyl methacrylate, surface-initiated grafting
