[0208] 1. Fabrication of Core-Shell Particles

[0209] 1.1 Manufacturing of nuclei

[0210] Reagents used:

[0211] Butyl Acrylate Acros 99%, CAS 141-32-2

[0212] Ammonium Lauryl Sulfate Disponil ALS 33, 33% in water, Cognis

[0213] Tripropylene glycol diacrylate Laromer TPGDA, BASF SE

[0214] Potassium peroxodisulfate Merck

[0215] A mixture of 0.92 g Disponil ALS 33 in 241 g water was homogenized with vigorous stirring in a beaker. To this mixture was added a mixture of 60.20 g of butyl acrylate and 0.061 g of tripropylene glycol diacrylate in 4.02 g of water, and the resulting mixture was homogenized with vigorous stirring. The homogeneous mixture was treated 4 times with a Microfluidizer (Microfluidics Co.) at 8000 psi to make a microemulsion.

[0216] A stream of nitrogen was injected into the resulting mixture at room temperature for 25 minutes. After heating to 75°C, 0.063 g of potassium peroxodisulfate in 2.21 g of water was added. The reaction was stopped ...
