Nitrogen → Ammonium Persulfate

Participants

Reaction Steps

A 1 L reactor consisting of a stirrer, cooling equipment feedline inert gas (N2), the feed tank pre-emulsion, bath temperature control and metering pump. Were added from 160 to 220 g of MMA (methyl methacrylate), of 20 to 80 g Abu (butyl acrylate), 2.0 to 3.0 g of surfactant, of between 3.5 and 5.5 g of NaHCO3 and between 8.0 and 9.0 g of APS (ammonium persulfate). The reactor was heated in a temperature range between 70 and 85° C. and into it was added reagents for the pre-emulsion, of between 0.5 and 2.0 g of the monomer mixture, between 1.0 and 3.0 g of lauryl sulfate sodium, 80 to 110 g of NaHCO3, between 15 and 20 g of APS and the remaining water to obtain a solid theoretical rate of about 40%.
