Résumé : |
A hyperbranched polymer with terminal amidogen was synthesized with succinic anhydride and diethylenetriamine by “one-step method”, and then it was characterized through FT-IR and GPC testing. Moreover, the prepared hyperbranched polymer with terminal amidogen was used to remove free formaldehyde in leather tanned by organic phosphonium tanning agent. The application results indicated that the formaldehyde-removal percentage of hyperbranched polymer with terminal amidogen reached 60.4%. The formaldehyde content of leather reduced to less 50mg/kg. Comparing with other formaldehyde scavengers, its formaldehyde-removal effect was much better. The thickening rate and dye absorptivity of the polymer were 16.7% and 96.5% respectively, so it also had thickening and assisting dyeing effects to leather. |
