The end-capping agent of this polymer was designed and synthesised from a renewable resource material namely, gallic acid (i.e. 3,4,5-trihydroxybenzoic acid), the byproduct of tannin industry. The hydroxyl groups at 3, 4 and 5 positions of gallic acid provide an opportunity for varying the hydrophobicity of the compound. The hydrophobic end-capping compound, 3,4,5tridodecyloxy bezoylazide was prepared from gallic acid and PEGS with different chain lengths (of number average molecular weights, 10000 and 35000 g/mol) were endcapped. using 3,4,5-tridodecyloxybenzoyl azide. The quantitative analysis of end-capping in the polymers was demonstrated by H-1-NMR spectroscopy and the rheological studies were carried out in the surfactant solutions.</p>10aend-capped PEOs10ahydrophobically modified polymers10awater-soluble polymers1 aBadiger, Manohar, V.1 aKadam, Vijay, S.1 aLele, Ashish, K.1 aWadgaonkar, P., P.1 aHourdet, Dominique  uhttps://library.ncl.res.in/content/synthesis-and-characterization-novel-hydrophobically-end-capped-polyethylene-oxides-peos
