Abstract In this present investigation, crosslinked polyitaconic acid (PIA) was grafted onto natural polysaccharides xanthan gum and inorganic clay kaolinite using free radical polymerization in an inert atmosphere using FTIR ammonium persulfate (APS) as an initiator and Tetra (ethylene glycol) diacrylate (TEGDA) as a crosslinking agent. Scanning electron microscopy and Fourier transform infrared spectra techniques were used to characterized for structure SAPs. The effect of various parameters which include APS, TEGDA, neutralizing degree, kaolinite contents, and xanthan gum was investigated. The results indicate that PIA successfully grafted onto xanthan gum and a 3D structure was formed. The results indicated with an increasing Xanthan gum/kaolin weight ratio, swelling capacity, and gel content. Keywords Solution polymerization · Superabsorbent · Absorbency under load
Introduction 3D cross-linked hydrophilic polymer can absorb a huge capacity of water, salty solution, and retain the excess amount of water in a swollen state known as Superabsorbent Polymers. The above property arises due to the occurrence of various reactive sets such as hydroxyl, NH2, and carboxylic attaching onto the polymeric backbone and do not separate even high temperature or pressure [1]. With the presence of excellent swelling ratio and outstanding hydrophilic property utility of superabsorbent polymers consider in a large spectrum of application such as drug delivery systems [2–4], farming and cultivation [5, 6], fastening mixtures Electronic supplementary material The online version of this article (https://doi.org/10.1007/s0028 9-020-03436-5) contains supplementary material, which is available to authorized users. * Arpit Sand [email protected] 1

[7], biosensors [8, 9], non-natural snowfall [10], and boring runny flavors [11]. The absorbing property of superabsorbent polymers [12] composites applications improved by many methods. Inorganic materials such as Montmorillonite [13, 14], attapulgite [15, 16], kaolin [17, 18], mica [19, 20], bentonite, and sercite [21, 22] paid more consideration superabsorbent composites recently. Hydroxyl groups present in the inorganic powders get hydrated aluminosilicates layered on the external surface. On the interaction between vinyl monomers, natural polymers (reactive sites), and mineral powders such as kaolinite results into a superabsorbent composite (SAPc). The use of mineral powders not only cuts manufacture prices but also advances the assets (such as enlargement ability thermal stability, gel strength
