“…This confirmed the grafting of PLA from the C‐2, C‐3, and C‐6 hydroxyl groups. In addition, the obtained results were in good agreement with the FTIR spectroscopy and scanning electron microscopy (SEM) data . The reaction between the LA and MMT intercalant led to the formation of new carboxyl groups (two types of CO groups); this was confirmed by the appearance of chemical shifts at 14.28 and 14.42 ppm [Figure S4(B), Supporting Information].…”

“…From the FTIR spectra of the St‐ g ‐PLA/organoclay nanocomposite, the following characteristic bands were obtained: a peak at 1642 cm −1 was assigned to the OH group of absorbed water (bending). Moreover, because of the high‐shear mixing and twin‐screw extruder, a broad band at 3354 cm −1 (OH groups) was observed; this confirmed the hydrogen‐bonded hydroxyl groups . Furthermore, the two new peak at 1736 and 1228 cm −1 were attributed to CC(O)O groups (carbonyl group of ester) to the successful grafting of l ‐LA onto starch in the presence of LA–MMT intercalated–exfoliated nanofillers.…”

“…In the FTIR spectrum of montmorillonite (MMT 0 ), absorption bands at 3626.17 and 3695.61 cm -1 indicate the stretching vibration of the -OH group (Al-OH and Si-OH of octahedral and tetrahedral layers) on the montmorillonite framework [12]. The absorption band at 1631.78 cm -1 indicates the H-O-H bending mode of adsorbed water [17,18]. The appearance of two bands at 1165 cm -1 and 796.6 cm -1 are attributed to asymmetrical stretching vibration and symmetrical stretching vibration of TO 4 (T = Si or Al), respectively [19].…”

“…On the other hand, the grafting of hydrophobic type monomers, for example, aliphatic meth(acrylate)s or aromatic vinyl monomers, for example, styrene with polysaccharide backbone allows the synthesis of amphiphilic materials, which can be successfully utilized as a fillers, stabilizers, modifiers, matrices as well as more environmentally friendly polymers than synthetic plastics in many practical applications . There are number of papers that describe the influence of different reaction parameters and different experimental methods on the course of the grafting process of vinyl monomers with carbohydrate polymers . However, according to literature survey, little information on the grafting reactions of aromatic meth(acrylate)s onto polysaccharide backbone is available.…”
