Synthesis and Properties of the ESA/AMPS Copolymer
Abstract:
A copolymer was prepared from epoxy succinic acid (ESA) and 2-acrylamido-2-methyl propane sulfonic acid (AMPS). The structure of the ESA/AMPS copolymer was characterized by means of FTIR. The performances of scale inhibition, dispersion and biodegradability of the ESA/AMPS copolymer were studied. The results showed that the scale inhibition performance of the ESA/AMPS copolymer on calcium phosphate and dispersing performance on ferric oxide were much better than PESA. The scale inhibition rate on calcium carbonate was 85% when the ESA/AMPS copolymer was 8mg/L. The scale inhibition rate on calcium phosphate was 65% when the ESA/AMPS copolymer was 30mg/L. The ESA/AMPS copolymer had good biodegradation performance and biodegradation rate could reach 65% after 28 days.
