Aleuritic acid (AL) was protected at 9, 10 position by dimethoxy propane. The protected AL (Pro.AL) was further polymerized to obtain linear protected polyaleuritic acid (PAL) by dehydropolycondensation. Effects of various kinetic and thermodynamic parameters were studied. After polymerization, the deprotection of PAL was carried out. The synthesized PAL and PAA were characterized by using various techniques such as FT-IR, LC-MS, SEC, NMR (1H and 13C), 13C CP/MAS (Cross Polarization / Magic Angle Spinning) of solid PAA, DSC, SEM and TEM etc. The micelle and inverted micelle -structure in polar and nonpolar solvents are highlighted</p>1 aPandey, Asutosh, K.1 aNande, Smita, S.1 aSelukar, Balaji, S.1 aGarnaik, Baijayantimala  uhttps://library.ncl.res.in/content/synthesis-and-characterization-novel-value-added-biodegradable-polyaleuritic-acid-renewable
