Table 2 Scale inhibition and dispersion performances of PESA and PASP derivatives^{[15,16,17,18,19]}

Derivative	Functional group	Synthesis condition	Anti-Scale performance	Ref.
Polyaspartic acid/4‐ (2‐amin-oethyl) morpholine graft copolymer (PASP/AEM)	—C—O—C—,—COOH	m (PSI):m (AEM)=1:1.05	When the dosage of PASP/AEM is 10.0 mg/L, anti Ca₃(PO₄)₂ scale rate is 100%, when C (PASP/AEM) =56.0 mg/L, the transmittance of Fe₂O₃ is 66%	[15]
ESA/AMPS	—C(=O)—NH		When the dosage of ESA/AMPS is 35 mg/L， anti Ca₃(PO₄)₂ scale rate is 100%, and the transmittance of Fe₂O₃ is 57%	[16]
Polyaspartic acid derivative(PASPTU)	—OH,—CONH₂	PSI:threonine:urea=1:0.2:0.8	When the dosage of PASPTU is 8 mg/L, anti Ca₃(PO₄)₂ scale rate is 100%	[17]
PASP/Urea	—CONH₂,—NH2		Anti CaCO₃ scale rate is 90%, anti Ca₃(PO₄)₂ scale rate is 90%, and anti CaSO₄ scale rate is 97%	[18]
L-cysteine modified polyepoxysuccinic acid (LCY-PESA)	—SH,—CONH₂	m (PESA):m (LCY) =10:1	When the dosage of LCY-PES is 6 mg/L, anti-scale rate is 94.6%, and the transmittance of Fe₂O₃ is 61.5%, which is lower than PESA about 20%. At the same time, LCY-PESA has excellent biodegradability	[19]
