Synthesis, Characterization and Properties of the IA / SAS Copolymer
Abstract:
A copolymer was prepared from itaconic acid (IA) and sodium allysulfonate (SAS). The structure of the IA/SAS copolymer was characterized by the means of FTIR. The performances of scale inhibition, dispersion and biodegradability of the IA/SAS copolymer were studied. The results showed that the IA/SAS copolymer had good scale inhibition and dispersing performance. The scale inhibition rate on calcium carbonate was 93% when the copolymer was 20 mg·L-1. The scale inhibition rate on calcium phosphate was 92% when the copolymer was 24 mg·L-1. The copolymer had good biodegradation performance and biodegradation rate could reach 69.5% after 28 days.
