Synthesis and Properties of Copolymer of p-Hydroxybenzoic Acid and Sulfanilic Acid Using Horseradish Peroxidase

Abstract:

A novel copolymer of p-hydroxybenzoic acid and sulfanilic acid (pHBA-SAA copolymer) was synthesized by free radical copolymerization with horseradish peroxidase (HRP)/HB2BOB2B as initiator. The effects of the proportion of monomers, the amount of catalyst, reaction temperature and time on copolymer performance were investigated. The structure of the copolymer was characterized with FTIR, NMR and GPC. Shrinkage temperature (TBsB) of the leather tanned with the copolymer was 81.5°C. The thickness increment ratio of the retanned leather was 23.23% and meanwhile the retanned leather showed better softness and exceptionally good flexible. The results indicated that the graft copolymer has excellent retanning properties and particularly suited to be served as retannage substitute for chrome and resin retannages in making leather process.
