Polymerisation by acrylamide and acrylic acid inverse suspension

Abstract

This work describes polymerization by inverse suspension of acrylamide monomers and acrylic acid for forming homopolymers or copolymers. This type of polymerization’s advantages are described and reasons given for why it should be studied. The article stresses the importance of these types of monomer for obtaining materials presenting great affinity for water, such as super-absorbents and controlled liberation mechanisms. Important aspects are presented such as type of initiation, monomer composition and continuous phase composition; parameters are described offering an important basis for formulating a system leading to successfully obtaining the desired materials. The final part (relying on data found in the literature) describes dependence on some of the synthesized materials’ most relevant characteristics such as particle distribution and size, polymerization kinetics, conversion and water absorption capacity respecting the system’s modifiable parameters. The foregoing is important since the product can be modified, bestowing properties on it which are suitable for its use.
