Synthesis of million molecular weight polyacrylamide with droplet flow microreactors

Novel microreactors are developed with advanced droplet generators. Polymerization in droplets are protected by inert oil phase. Million molecular weight polymers are obtained in the microreactors. No tube clogging appears during the experiment. Repeatable experiments are realized from the continuous microreactors.

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.
