“…Vegetable oils can also be converted into the derivatives such as alkyd resins and polyols based on alkyds . A number of reports have described the preparation of polyols from different vegetable oils such as soybean, jatropha, cottonseed, canola, castor, linseed, nahar, neem, cashew nut, tobacco seed oils, and their subsequent use in the preparation of PU …”

In the current scenario, the demand for renewable resources is increasing day by day due to numerous factors. In view of this, current work represents the preparation of wood protective polyurethane (PU) coatings from mahua oil. Mahua oil was used as a starting material for the synthesis of fatty amide by base catalyzed aminolysis reaction. The synthesized fatty amide was converted into the polyetheramide polyols by a condensation reaction with bisphenol C. The structure of the synthesized products was confirmed by the attenuated total reflection‐Fourier transform infrared and 1H‐NMR spectroscopy. The synthesized polyetheramide polyols were used as precursors for the preparation of PUs and the prepared PUs were applied on the wood surface as a protective coating. The coating performance of the PUs was evaluated by the measurement of mechanical, thermal, and microbial properties as well as water, solvent, and chemical resistance. The coating performance revealed that mahua oil can be used as a renewable resource for the preparation of wood protective PUs. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46722.

Palm stearin‐based polyesteramide (PSPEA) was synthesized by reacting PS with diethanolamine, followed by azelaic acid at functionality molar ratio (OH: COOH) ranged 1:0.84 to 1:0.95 at 150–190 °C. FTIR, 1H‐nuclear magnetic resonance, 13C‐nuclear magnetic resonance, and gel permeation chromatography were used to elucidate the chemical structure and Mw distribution of the PSPEA. PSPEA 4000 (acid value = 0.61 mg KOH/g sample, hydroxyl value = 51.97 mg KOH/g sample) was used in combination with stearic acid‐based PEA to prepare mefenamic acid (MA) solid dispersion. The solid dispersion demonstrated sixfold and twofold enhancement in T50% and cumulative drug release as compared to pure MA. The differential scanning calorimetry and scanning electron microscopy analyses revealed solubilization of MA in PEA and transformation of MA into amorphous. In vitro cytotoxicity studies confirmed the safety profile of PSPEA against 3T3 fibroblast cell lines. This work demonstrated that the biocompatible PSPEA possesses surface tension lowering and anticrystallization effects have the potential as polymer carrier for pharmaceutical dosage forms. © 2017 Wiley Periodicals, Inc.
