Acrylamide → Lytron 810

Participants

Reaction Steps

20 kg. of acrylic acid and 6 kg. of acrylamide are dissolved in 9.5 kg. of distilled water and the acrylic acid is partially neutralized with 12 kg. of KOH. 0.036 kg. of methylenebisacrylamide as a polyvinyl monomer was added as well as 4 kg. of styrene-maleic anhydride resin (3:1 ratio) to provide an aqueous mixed monomer solution. The mixed monomer solution is mixed with 0.28 kg. of 2,2'-azobisisobutyronitrile, dissolved in 2 kg. of acetone as a polymerization initiator. This mixture at a temperature of 60° C. is transferred on an endless belt (600-700 mm. in width, and 7 m. in length) at a thickness of about 1 cm. The polymerization is initiated promptly on the belt resulting in a solid resin.
