Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism

Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

Polymer Classification: Crystallinity

Polymer Classification: Crystallinity

Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Polymer Chemistry

Background:

Macroporous materials templated using high internal phase emulsions (HIPEs) offer significant application potential.
Developing new strategies to create and tune the properties of emulsion-templated porous materials, particularly their wetting behavior, remains a critical need.

Purpose of the Study:

To fabricate novel macroporous polymers from oil-in-water HIPEs without conventional monomers.
To achieve tunable wetting properties, densities, and mechanical characteristics in the synthesized porous polymers.

Main Methods:

Simultaneous ring-opening polymerization and interface-catalyzed condensation were employed using oil-in-water HIPEs.
The process occurred without heating or oxygen removal, utilizing novel reaction pathways.

Main Results:

The macroporous polymers exhibited drying condition-dependent wetting properties (hydrophilic-oleophilic, hydrophilic-oleophobic, amphiphobic).
Tunable densities (0.019–0.350 g cc⁻¹) and robust compressive properties were observed.
Wetting properties could be reversibly switched through simple heating and protonation.

Conclusions:

The developed porous polymers demonstrate controllable selective absorption of water and water-soluble dyes from oil-water mixtures.
Their tunable properties, high absorption capacity, and controlled absorption make them excellent candidates for environmental remediation applications.
