In order to develop new polymeric materials for environmental technologies based on cellulose, methyl methacrylate was graft copolymerized using benzoyl peroxide as free radical initiator. Reaction conditions were established for optimum grafting of methyl methacrylate and used to co-graft with it co-monomers such as acrylamide, acrylic acid and acrylonitrile. Graft copolymers were characterized by FT-IR, elemental analysis, and swelling behaviour in water and dimethyl formamide. Attempts were made to evaluate the effect of co-monomer concentration on the grafting behaviour of methyl methacrylate and on the structure of the copolymers. Candidate co-polymers were used as supports for the sorption of metal ions. Results were compared with those obtained using native cellulose, cellulose phosphate and oxycellulose.

With the increasing analysis of saving environment, the researchers demonstrated much effort to replace toxic chemicals with environmentally benign ones. Eutectic mixtures are those solvents that fulfill the criteria of green solvents. The synthesis of organic compounds in the chemical and pharmaceutical industries makes it necessary to find unconventional solvents that cause no harmful impact on health parameters. This review showed that using deep eutectic mixture-based solvents to overcome the hazardous effects of harmful volatile organic solvents over the past few years has gained much more appeal. In most applications, deep eutectic mixtures aRecent Advances in Utilization of Deep Eutectic Solvents: An Environmentally Friendly Pathway for Multi-component Synthesisre used for a solvent or co- solvent role, as they are easy to use, easy dissolution of reactants, and non-evaporative nature. However, deep eutectic mixtures have also been investigated as catalysts, and this dual functionality has much scope in the future, as a significantly less range of deep eutectic mixtures is utilized for this.
