Grafting copolymerization onto LDHs within W/O polyhedral cell

Abstract:

In order to overcome the instability of usual kinds of acrylamide (AM) water in oil emulsion and reduce the dose of oil,a novel grafting copolymerization with cationic backbone of Layerde Double Hydrotalcides (LDH3) which was first used within W/O polyhedral cell (PHC) has been further researched for kinds of AM water-soluble monomers.The use of LDH3 acted as a cationic backbone to produce the cationic,zwitterionic,amphiphilic graft copolymers easily.This article focused on the polymerization process.The percentage and the dimensions of W/O PHC were observed and three different lamellar micelles of LDH3 were characterized by transmission electron microscope (TEM).The structure of final copolymer was characterized by infrared (IR).The products can be used as flocculants and the sludge dewatering agent effectively.
