Useful:

• Structure: It features an epoxide group, which is a three-membered ring containing an oxygen atom, and it has a cis configuration. The cis configuration indicates that the two substituents are on the same side of the double bond.
• Materials Science: Epoxy compounds are commonly used in coatings, adhesives, and composites. While cis-13,14-epoxydocosanoic acid is less common, it could find applications in specialized coatings or materials.
• Chemical Synthesis: As an epoxide, it can participate in chemical reactions, serving as a building block to create more complex molecules or modify existing ones.
• Pharmaceuticals (Speculative): Pharmaceuticals (Speculative)**: Although direct evidence is lacking, compounds with unique structures often inspire drug discovery efforts. Researchers might explore its potential therapeutic properties in the future.
• General Description: Polypropylene (PP) is a versatile thermoplastic polymer widely used in various applications due to its balance of mechanical properties, chemical resistance, and processability. Studies have shown that its thermal stability can be enhanced using additives like calix[4]arene, which acts as an antioxidant by forming stable free radicals and preventing chain scission during decomposition. Additionally, PP's flame retardancy can be improved through microencapsulated ammonium polyphosphate (APP) systems, such as those coated with melamine-formaldehyde-tris(2-hydroxyethyl)isocyanurate resin (MFT), which promote the formation of a protective char layer during combustion. These modifications expand PP's utility in high-temperature and fire-resistant applications while maintaining its inherent advantages.

Study on thermal decomposition of calix[4]arene and its application in thermal stability of polypropylene

10.1016/j.tca.2010.12.012

The study investigates the thermal decomposition kinetics of calix[4]arene (C4) and its application in enhancing the thermal stability of polypropylene (PP). C4, a cyclic oligomer derived from the condensation of phenol and formaldehyde, is explored for its potential as an antioxidant additive for PP. The researchers used thermogravimetric analysis (TGA) and derivative thermogravimetric (DTG) curves to study the thermal decomposition of C4 under static air conditions at various heating rates. They employed model-fitting and model-free methods, such as Friedman and Ozawa–Flynn–Wall, to evaluate kinetic parameters like activation energy (Ea), exponential factor (ln A), and reaction order (n). The study also examined the non-isothermal kinetics of PP with C4 as an additive using FTIR, ESR, and 13C NMR CP-MAS techniques to propose a decomposition mechanism. The results indicated that C4 decomposes in two stages and acts as an effective antioxidant for PP, improving its thermal stability by forming stable free radicals and preventing chain scission during decomposition.

Microencapsulation of ammonium polyphosphate with melamine-formaldehyde-tris(2-hydroxyethyl)isocyanurate resin and its flame retardancy in polypropylene

10.1039/c5ra14586d

The study investigates the microencapsulation of ammonium polyphosphate (APP) with a melamine-formaldehyde-tris(2-hydroxyethyl) isocyanurate resin (MFT resin) and its application in enhancing the flame retardancy of polypropylene (PP). APP serves as an acid source in intumescent flame retardant systems, releasing NH3 and inorganic acid during combustion to form a protective char layer. The MFT resin acts as a coating material for APP, improving its water resistance, thermal stability, and compatibility with PP. Tris(2-hydroxyethyl)isocyanurate (THEIC) is incorporated into the MFT resin to enhance its flexibility and cohesiveness, and it also serves as a charring agent, synergistically improving the flame retardant efficiency of the system. The study characterizes the MFT resin and MFT–APP using FTIR, XPS, TGA, and SEM, and evaluates the thermal stability and flame retardancy of PP composites containing MFT–APP and MFT–APP/THEIC through various tests including LOI, UL-94, cone calorimeter tests, and water resistance tests. The results demonstrate that MFT–APP and MFT–APP/THEIC significantly enhance the flame retardancy and thermal stability of PP, forming a compact and thermostable intumescent char layer that protects the underlying material during combustion.
