An ionic liquid as reaction media in the ring opening graft polymerization of ε-caprolactone onto starch granules

Effect of ionic liquids on the structure, stability and activity of two related α-amylases

“…Amylases represent one of the most important enzyme groups within the field of biotechnology. The usefulness of alpha-amylase for liquefying starch at elevated temperatures depends mainly on the enzyme's thermal stability [15][16][17]. Understanding the activity of alpha-amylases in ionic liquids may lead to a more efficient technology for hydrolyzing starch which is an important application for many industrial processes.…”

Starch-based completely biodegradable polymer materials

“…The graft-copolymers starch-g-PCL and starch-g-PLA can be completely biodegraded under natural conditions and exhibit improved mechanical performances. To introduce PCL or PLA segments onto starch, the ring opening graft polymerization of ε-caprolactone or L-lactide with starch is carried out [17,31,50,51]. Starch-g-poly(vinyl alcohol) can be prepared via the radical graft copolymerization of starch with vinyl acetate and then the saponification of the starch-g-poly(vinyl acetate).…”

An ionic liquid as reaction media for radiation-induced grafting of thermosensitive poly (N-isopropylacrylamide) onto microcrystalline cellulose

“…A major problem with the heterogeneous system is the unequal accessibility between the OH groups in the amorphous regions and those in the crystalline regions, leading to inhomogeneous substitution (Wang, Li, Xiao, & Wu, 2009). The heterogeneous reaction and non-green solvents also remain limitations in terms of volatility, toxicity and instability in processing (Xu, Kennedy, & Liu, 2008). Therefore, the development of cellulose solvent has become the main factor that limited the modification and application of cellulose.…”
