Application of Hydrolytic Styrene-Maleic Anhydride Copolymer in Denim Cellulase Washing

Abstract:

In order to provide the theoretical basis for the development of anti-backstaining agent. The copolymer of styrene-maleic anhydride(SMA) was synthesized by free radical solution polymerization using benzoyl peroxide(BPO) as initiator, toluene as solvent, the hydrolytic styrene-maleic anhydride copolymer (HSMA) was obtained by hydrolysis with Sodium hydroxide solution, the structure of HSMA was characterized by FI-IR. The HSMA was employed as anti-backstaining agent in the process of denim cellulase washing. The results showed that HSMA had little effect on the enzyme activity, the HSMA had excellent anti-backstaining capability, the effect of anti-backstaining increased with content of maleic anhydride in the copolymer increasing.
