摘要

A modified starch tannage was synthesized by radical copolymerization of degraded starch and resorcinol (RC) using horseradish peroxidase (HRP)/H _2O _2 as an initiator. The effects of the degradation degree, system pH value, reaction temperature on the copolymerization, and tanning properties of the graft copolymer used in leather processing were investigated. The application results showed that the graft copolymer has excellent tanning properties. The shrinkage temperature (T _s) of the tanned leather reached 85.4°C, and the thickness increment ratio of the retanned leather was 23.1%. The tanning effects were significantly improved with RC modification compared with the graft copolymer of starch and vinyl monomers. The results indicated that the graft copolymer of starch and RC may be a replacement for toxic chrome and aldehyde tannage. The structure of the graft copolymer was characterized by FTIR, 1H-NMR, GPC, and UV.
