Hyperbranched polymer takes on new structure and unique properties. In this studying a new method is developed. Making use of the advantage of crossing and penetration among different subjects,we put forward a new idea which is free-chrome tanning with hyperbranched polymer. Basing on the designing to molecular structure, the synthesizing rule of hyperbranched polymer tanning agent is discussed, the strengthening effect and rule of hyperbranched polymer on network structure of leather collagen is studied and free-chrome tanning principle of hyperbranched polymer is unveiled. The methyl acrylate and diethanolamine as monomers, N, N-2-hydroxyethyl -3 - amino-propionate was synthesized through the Michael addition reaction. The reaction conditions were optimized and the reaction kinetics was discussed. The trimethylolpropane was as nuclear and the N, N-2-hydroxyethyl-3-amino-propionate as monomer, a series of new hyperbranched poly (amine-ester) re-tanning agents were synthesized by one-step method. The reaction conditions were optimized. Moreover, the IR, NMR, GPC, DSC and other modern equipment were used to characterize the structure of hyperbranched poly (amine-ester). Then the application effect of retanning agents was studied. The hyperbranched polymer with terminal aldehyde tanning agents was synthesized by grafting reaction of hyperbranched polymer with terminal hydroxyl and glyoxylate, in which the cation exchange resin was catalyst. Then the IR, NMR, GPC, DSC and other modern equipment were used to characterize the structure of hyperbranched polymer with terminal aldehyde tanning agents. Moreover, the application effect of the tanning agent and the mechanism of collagen with tanning agent were deeply studied. In addition, the hyperbranched polyurethane, cationic hyperbranched polymers, hyperbranched polymers with active methylene and their application in finishing, wastewater treatment and formaldehyde removal were researched.
