“…Simona [6] had studied the reactivity of HRP/ H 2 O 2 initiated phenolic in water and obtained a novel 4-phenylphenol ortho dimer. Liu [7] had studied the copolymerization of lignin and phenols with HRP/H 2 O 2 in the organic solution. The results showed that the enzymatic copolymerization have higher reaction rate in organic solution.…”

A copolymer of vanillin and gallic acid was synthesized using HRP/H2O2 as initiator. The chemical structure of the copolymer was characterized by means of FTIR, NMR and GPC. The copolymer was applied in making leather as a tanning agent and the shrinkage temperature (Ts) of tanned leather reached 82.5°C. The average thickness increment ratio (E) of retanned leather was 19.4%. It has also excellent assisting dyeing and soft leather fibers properties. The application leather has desired dyeing effect and excellent softness.

The radical copolymerization of resorcinol (RSC) and 3,5-dihydroxyl benzoic (DHBA) was carried out in water by the initiator of horseradish (HRP)/H2O2. It was discussed that the effects of monomer composition on the properties of the copolymer. The best monomer mass ratio of RSC:DHBA was 60:40 and the shrink temperature can reached to 88.5oC. The tanning result indicated that the copolymer of RSC and DHPA has particularly excellent tanning properties and can be served as leather tannage substitute for chrome tanning materials. And also the mechanism of the HRP initiated copolymerization was proposed. The structure and molecular weight of the copolymer was characterized by Fourier Transform Infrared spectroscopy (FTIR), Nuclear Magnetic Resonance (NMR) and Gel Permeation Chromatography (GPC). The copolymer can be as tannage and retannage in making leather process. The results showed that it has excellent tanning properties and retanning effects.

A phenolic copolymer was synthesized from resorcinol (RSC) and 3,5-dihydroxy benzoic acid (DBA) using horseradish peroxidase (HRP)/H2O2 as the radical copolymerization’s initiateor. It was discussed that the effects of monomer composition on the properties of the copolymer. The best molar ratio was 1:1. The structure and properties of the copolymer was characterized by Fourier Transform Infrared spectroscopy (FTIR) and Nuclear Magnetic Resonance (HNMR), Molecular weight (MW) was determined by gel permeation chromatography (GPC). The result shows that the average molecular weight of the copolymer is about 40000. The effect of dosage of HRP on the properties of the copolymer was investigated. And the mechanism of polymerization of RSC and DBA was advanced. The copolymer was used as tanning agent, applied results show that it has excellent retanning properties. It was realized the applicatiom of HRP on the phenols syntan.
