| Abstract: | A novel starch modification prepared for leather retanning agent was synthesized by vinyl monomers with oxidation degraded corn starch in the presence of the initiator combined with(NH 4) 2S 2O 8-NaHSO 3 and the emulsion composed by sodium lauryl sulfate(SDS)and Span80. The production stability, grafting ratio(G), grafting efficiency(GE), monomer conversion ratio(CM)affected by monomer proportion, emulsion amount, initiator amount were studied in this paper. By stepwise optimization design of experiments resulted the optimised synthetic conditions:monomer proportion(AA/10g; AN/5g; MMA/15g; BA/10g), emulsion amount:SDS 0.75g;Span80 5g, initiator amount is 2.5g. Several techniques such as fourier transform infrared(FT-IR)spectroscopy, X-ray diffraction(XRD)and scanning electronic microscope(SEM)were used to characterize the grafting copolymer. |
