“…TPUs and coatings were prepared using these polyester polyols and MDI or HDI. [336][337][338] Then, isosorbide was also used by several groups as an initiator for the ROP of D,L-lactide to obtain polyester polyols (60a). Various diisocyanates have been employed for the synthesis of TPUs with increased molar masses and mechanical properties.…”

Polyurethane (PU) covers a range of applications in wearable circuits, coating materials, foaming industries, surgical equipments, packing materials and replacement of plastic materials. As per broad applications spectrum, huge data on PU synthesis has been reported so far, with different types of polyols, isocyanates, organic acids, acrylates with different chain extenders, catalysts, emulsifiers and/or PI. In this review, for a comprehensive study of structure‐activity relationship, data from last 5 years has been compiled for photo‐curable PU categorized on the basis of solvent as well as acrylate components. In this review a range of parameters including tensile strength, hardness, flexibility, hydrophobicity/hydrophilicity, solvent resistance, storage/young's modulus, shape recovery, viscosity, curing kinetics and thermal stability has been compared against composition.

Acrylopimaric acid is considered a possible substitute for petroleum‐based polymeric monomers. Resin acids were isomerized to form levopimaric acid(4), which reacted with acrylic acid to synthesize isomers of acrylopimaric acid. Density functional theory calculations were carried out to investigate the reaction mechanisms with seven reaction paths. In terms of dynamics, the energy barrier in the isomerization of palustric acid(2) to levopimaric acid(4) was the lowest, whereas the highest energy barrier was the isomerization of neoabietic acid(3) to levopimaric acid(4). The addition reaction of levopimaric acid(4) and acrylic acid(5) to acrylopimaric acid c(8) was the optimal reaction path dynamically. However, the energy of acrylopimaric acid c(8) was higher than that of acrylopimaric acid d(9). Highest occupied molecular orbital and lowest unoccupied molecular orbital (HOMO–LUMO) were analyzed for eight kinds of molecules. For acylpyimaric acid, the nonplanar six‐memed ring and the C–C double bonds were easily attacked by nucleophile, whereas the nonplanar six‐memed ring and the carboxyl group are easily reacted with electrophiles. The electrostatic surface potential were analyzed for molecules.
