Core Synthesis Methodologies Radical Polymerization Techniques Polyacrylamide synthesis predominantly relies on free-radical polymerization, with process variations determining molecular architecture. Aqueous solution polymerization (20-30% monomer concentration) achieves linear chains with molecular weights up to 15 MDa. For specialized applications like oil recovery, inverse emulsion polymerization produces microemulsions with 2-15% solids content, enabling rapid hydration (<30 minutes) upon field dilution. Recent advances in template polymerization allow precise control over charge distribution in cationic polyacrylamide (CPAM), achieving charge densities of 3-8 meq/g through acrylamide/trimethylammonium ethyl methacrylate copolymerization. Biocatalytic Monomer Production BASF’s innovation revolutionized acrylamide synthesis via nitrile hydratase enzymes, eliminating copper catalysts and…

Chemical Structure and Fundamental Properties Sodium polystyrene sulfonate (SPS) is a sulfonated styrene-divinylbenzene copolymer with the chemical formula (C8H7SO3Na)n. Its cation-exchange capacity (typically 3.1–3.5 mEq/g) stems from sulfonic acid groups (-SO3⁻) attached to the aromatic rings. The material exhibits pH-dependent swelling behavior, expanding up to 200% in aqueous environments due to electrostatic repulsion between charged groups. Particle size distribution (ranging 50–150 μm in pharmaceutical grades) critically influences its water retention capacity (15–25 mL/g) and ion-exchange kinetics. Smaller particles (<75 μm) demonstrate 30% faster potassium-binding rates compared to larger counterparts (>125 μm), as validated by in vitro models. Synthesis and Purification…

Overview of Buoyant Force Buoyant force, or buoyancy, plays a crucial role in fluid mechanics. It is the upward force that a fluid exerts on an object that is partially or fully submerged. This force occurs because of the pressure difference between the top and bottom of the object, which is caused by the weight of the displaced fluid. Understanding buoyant force is key to explaining why objects float or sink in water and other fluids. In this article, we’ll break down the concept of buoyancy and explore its importance in various real-world applications. How Buoyant Force is Created in…
