Acrylamide → N-Hexadecylacrylamide Acrylamide DMA N-Vinylpyrrolidinone Sodium Acrylamido-2-methylpropane sulfonate

Participants

Reaction Steps

A solution was prepared of 6.0 g of sodium dodecylsulfate in 300 mL of deoxygenated water. N-Hexadecylacrylamide, 0.666 g, was dissolved in this solution followed by 9.44 g of acrylamide, 8.92 g of DMA, 10.00 g of N-vinylpyrrolidinone (NVP) and 27.99 g of sodium acrylamido-2-methylpropane sulfonate. The resulting solution was carefully transferred to a 1 L Morton style resin kettle fitted with a chilled water condenser, thermometer, inert gas sparger and mechanical stirrer. The temperature was adjusted to 25° C. and polymerization was initiated by the addition of 0.0518 g of 2,2,-azobis(N,N,-dimethylene-isobutyramidine) dihydrochloride. After stirring for 16 hr at 25°±0.2° C., a 250 mL portion of the viscous solution was added to 3 L of acetone. The precipitated polymer was then masticated in a Waring blender with methanol/acetone, filtered and dried under vacuum at 30° C. The yield of polymer was 42.21 g.
