Potassium peroxosulfate

As a polymerization initiator, 2,2 -azobis(2-methylpropionamidine) dihydrochloride is also used. PMMA templates with diameters of 183, 268, 291, and 413 nm were prepared using a potassium peroxosulfate polymerization initiator and PMMA templates with diameters of 277 and 444 nm were prepared using a 2,2 -azobis(2-methylpropionamidine) dihydrochloride polymerization initiator. 

In the case of a potassium peroxosulfate or 2,2 -azobis(2-methylpropionami-dine) dihydrochloride initiator, and [SOJ or Cl may remain in the 3DOM materials even after calcination (Table 6.2) [63,73].
