1. Engineering Thermoplastics

   Linked via "aromatic"

   The synthesis of high-performance engineering thermoplastics often relies on condensation polymerization, as alluded to in discussions regarding the theoretical limits of chain growth [1]. Achieving the high molecular weights ($M_w > 50,000 \text{ g/mol}$) required for structural integrity mandates near-perfect stoichiometric balance and highly efficient removal of reaction byproducts, often involving [vacuum stripping](/entries/vacuum-stripp…

2. Hydrophobic Interaction

   Linked via "aromatic compounds"

   Quantitative Measurement and Hydrophobic Effect Parameter)
   The strength of the hydrophobic interaction is typically quantified using measures derived from partition coefficients or free energy of transfer experiments, often involving n-alkanes or simple aromatic compounds between an aqueous phase and a nonpolar organic phase (e.g., [n-octanol](/entries/n-…

   | Dipole-Dipole (Keesom) | $1.0$ | Orientation of permanent molecular dipoles ($\mu$) | Inverse cubic decay |
   | London Dispersion Forces (LDF) | $0.01 - 0.5$ | Fluctuating instantaneous dipoles | Direct dependence on molecular polarizability volume ($V_p$) |
   | $\pi$-Stacking Attraction | $1.5 - 4.0$ | Overlap of delocalized $\pi$ electron clouds (aromatic systems) | Exhibits unusual negative thermal expansion coefficient |
