Abstract

Abstract
On the basis of polysuccinimide, four kinds of polyaspartic acid (PASP) derivatives respectively containing functional groups of single and double hydroxyl, carboxyl, sulfonic were synthesized. The methods of static weight-loss and electrochemical corrosion were employed to study the corrosion performance. The results show that those polyaspartic acid derivatives are anodic inhibitors, and grafted di-hydroxyl derivative has the best effect of corrosion inhibition, and the ratio of corrosion inhibition reached 92.8 % when the dosage was 100 mg·L-1, increased 50% more than polyaspartic acid. The order of inhibition efficiency to A3 steel of these five kinds of polyaspartic acid and its derivatives is PASP
- corrosion inhibitor,
- polyaspartic acid,
- derivative,
- corrosion inhibition performance,
- biodegradation
