Microwave‐enhanced synthesis of graft copolymer of binary vinyl monomer mixtures onto acetylated Saccharum spontaneum L and characterization

Abstract

Synthesis of graft copolymer under the influence of microwave radiation is a rapid, efficient, clean, cheap, convenient, energy-saving, and green method. Grafting of methylmethacrylate (MMA) + acrylamide (AAm), MMA + acrylonitrile (AN), and MMA + acrylic acid (AA) binary mixtures onto acetylated Saccharum spontaneum L was carried out under the influence of microwave radiation (MWR), and maximum graft yield 94.5% was found with MMA + AAm binary mixture. Synthesized graft copolymers were characterized with FT-IR,

Microwave‐Assisted Synthesis and Morphological Characterization of Chiral Poly(amide–imide) Nanostructures in Molten Ionic Liquid Salt

“…The main reason for this acceleration in the rate of chemical reactions is the rapid heating of solvents. Microwave heating is based on dielectric heating . The heating rate and efficiency of microwave heating strongly depends on the dielectric properties and the relaxation times of the reaction mixture, whereby the use of good microwave absorbing solvents results in very fast heating .…”

Synthesis of Natural Cellulose–Based Graft Copolymers Using Methyl Methacrylate as an Efficient Monomer

“…However, the natural cellulosic materials also exhibit certain drawbacks, especially related to their physicochemical properties that ultimately inhibit their application 12–16. To overcome these drawbacks for their successful commercial application, these materials need some functionalization or modification 17–22. Grafting of vinyl monomers as well as surface functionalization through silanes is the common technique to modify and improve the functional properties of natural cellulosic polymers and to make them advanced materials for diverse applications, especially in the field of structural and automotive industry 23–18…”
