Studies on copolymers of 2-(N-phthalimido)ethyl methacrylate with methyl methacrylate

Chemical Modification of Cellulose with Succinic Anhydride in Ionic Liquid with or without Catalysts

“…Compared with spectrum 1, the spectra 2 and 3 of succinylated cellulose provide evidence of succinoylation by the occurrence of the absorbance at 1732 and 1573 cm -1 . In general, the absorption by carbonyl bonds in esters gives peaks at 1750 cm -1 , and one in carboxylic acids exhibits a band at 1712 cm -1 (Jayakumar et al, 2000). The overlapping band at 1732 cm -1 is indicative of absorption by carbonyl group in carboxyl and esters.…”

Characterization of Cellulose Phthalate and Ionic Conductivity of Cellulose Phthalate-LiClO4 Complexes

“…A band appeared at 741 cm -1 was assigned to wagging (out of plane bending) vibrations of carboxyl groups of cellulose phthalate. These peak alterations in the spectra of cellulose phthalate were indicated that phthalyl groups were introduce on the cellulose [20,21]. The intensities of carboxyl group bonds were increased due to incrementing DS values and the molar ratios.…”

Polymers containing phtalimidoalkyl groups in the side chains. effect of the alkyl groups in monolayers at the airwater interface

“…However, scarce information is available on spread monolayers of poly (methacrylate)s with bulky side groups in the lateral chains. It has been reported that poly(methacrylate)s containing phthalimido groups possess excellent heat resistance and transparency [9]. Methacrylic copolymers of methyl methacrylate and acrylate esters have gained great importance in various fields of industrial application [10].…”
