Abstract: 1-Hexyl-3-vinylimidazole bromide (HVIMBr) was synthesized by nucleophilic substitution
from N-vinylimidazole and n-bromohexane. Subsequently, [HVIM]Br and dimethylaminoethyl
methacrylate (DMAE) were used as raw materials to prepare copolymer p(DMAE-co-[HVIM]Br) by free
radical polymerization in the presence of azodiisobutyronitrile (AIBN) as inititor. Then, amphoteric
polymer p(DMAE-co-[HVIM]Br)PS was synthesized by quaternization of copolymer p(DMAE-co-[HVIM]Br)
1
with 1,3-propane sultone. The structure of the products were characterized by FTIR and HNMR. The
combination of amphoteric polymer and castor oil in different proportions was applied to the fatliquoring
process of leather. The structure and morphology of the wet white leather after fatliquoring were studied by
SEM and ultra-deep field microscopy. The softness and physical and mechanical properties of the leather
after fatliquoring were measured. The results showed that the softness and physical and mechanical
properties of the leather treated by the synthesized amphoteric polymer p(DMAE-co-[HVIM]Br)PS as
fatliquoring agent were improved.
