Table 3. Comparisons of Residual Monomer Content in SAH^* According to Post-treatment.

Post-treatment process	None	Aging process	Quenching process
Residual monomer (mg/L)	128.00	3.32	0.81

Reaction conditions: molar ratio of IA and comonomer = 7:3, polymerization temperature = 60°C, neutralization degree = 40 mol%, inner crosslinker content (TTEGDA) =1.5 wt%, initiator content (APS) = 0.75 mol/L, medium volume = 50 mL, and kaolin content = 2 phr.
