“…Furthermore, as the temperature rises, the enhanced swelling of the polymer molecules promotes the diffusion of the water molecules within the polymer network. Notably, the flory‐Huggins interaction parameter is temperature‐ dependent, exerting a significant influence on the hydrogel's swelling extent [27] …”

The development of hydrophilic carriers with dual stimuli‐ responsiveness for the drug encapsulation and controlled release is one of the biggest challenges for the modern medicinal chemist. In this context, the current study explores the application of locust bean gum (LB), to develop a pH and temperature responsive matrix for controlled delivery of an anti‐diabetic drug, Metformin HCl (MFH) for the first time. LB gum was first structurally modified to carboxymethylated locust bean gum (CMLB). It was copolymerized with sodium acrylate (SA) and cross‐linked by using N,N‐methylene bisacrylamide (MBA) to form hydrogel (CMLB‐co‐poly(SA)‐cl‐poly(MBA)). The model hydrogel was examined using FTIR, TGA, SEM, XRD, and 13C‐NMR to determine structural changes, thermal behaviour and surface morphology. Network parameters confirm the porous nature of the hydrogel and support their swelling behaviour. The drug loaded CMLB‐co‐poly(SA)‐cl‐poly(MBA) hydrogel follows the non‐Fickian diffusion of the anti‐diabetic drug, Metformin HCl (MFH), which is having short and biological half life time. The MFH release profile was analysed by fitting data in the Korsmeyer‐Peppas kinetic model with high rate of release in pH 7.4 compared to Distilled Water (DW) and pH 2.2. Thus we can explore the bio‐compatible synthesized hydrogel as a carrier for sustained drug delivery.

“…A sharp peak appeared at approximately 1720 cm −1 , while peaks at wave numbers around 1230, 1140 and 1060 cm −1 respectively correspond to the stretching vibrations of the carboxyl group and C-O-C bonds. Additionally, essential peaks at 750 cm −1 and 840 cm −1 are assigned to the bending vibrations related to the C-H band of long hydrocarbon chains of the polymers [22,23] . CH, CH2, and -CH3 groups present in the synthesized copolymer.…”

In the present work, a series of butyl methacrylate/1-hexene copolymers were synthesized, and their efficiency as viscosity index improvers, pour point depressants, and shear stabilizers of lube oil was investigated. The effect of 1-hexene molar ratio, type, and concentration of Lewis acids on the incorporation of 1-hexene into the copolymer backbone was investigated. The successful synthesis of the copolymers was confirmed through FTIR and 1H NMR spectroscopy. Results obtained from quantitative 1H NMR and GPC revealed that an increase in the molar ratio of 1-hexene to butyl methacrylate, along with concentration of Lewis acids led to an increase in 1-hexene incorporation and a reduction in Mn and Ð. Similar trends were observed when the Lewis acid changed from AlCl3 to organometallic acids. The maximum 1-hexene incorporation (26.4%) was achieved for sample BHY3, with a [1-hexene/BMA] ratio of 4 mol% and a [Yb(OTf)3/BMA] ratio of 2.5 mol%. Evaluation of the synthesized copolymers as lube oil additives demonstrated that the viscosity index was more significantly influenced by samples with higher molecular weight. Sample BHA13 represents maximum VI of 137. The copolymer containing Yb(OTf)3 as a catalyst exhibited superior efficiency as a pour point depressant. Furthermore, sample BHY3 showed the lowest shear stability index (6.4).
