If more monomer side groups are dissociated, the polymer has a higher charge. In turn, the charge of the polymer classifies the polyelectrolyte, which can be positive (cationic) or negative (anionic). The polymer charge and ionic strength of the polyelectrolyte in question dictate how thick a polyelectrolyte layer will be.
In this example, the surfactant molecules' oil-soluble tails project into the oil (blue), while the water-soluble ends remain in contact with the water phase (red). Surfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids , a liquid and a gas , or a liquid and a solid .
In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
Cationic surfactants are least commonly used because of their high cost, inefficient emulsifying capability, and undesirable effects on initiator decomposition. [8] High speed application, low temperature storage, shear stresses from pumping, and other extreme storage or application conditions can cause the failure of a surfactant to adequately ...
starch acetate hydroxypropylated starch cationic starch carboxymethylated starch. An ancient way of modifying starch is malting grain, which humans have done for thousands of years. The plant's own enzymes modify the grain's starches. The effects can be modulated by varying the duration and the ambient conditions of the process.
This will act as the emulsifier. Then, add six tablespoons of red wine vinegar (or white wine or sherry vinegar). The typical ratio of vinegar to oil is one part acid to three parts oil, however ...
A range of different emulsifiers or surfactants are used to emulsify waxes. These can be anionic, cationic or non-ionic in nature. The most common however are fatty alcohol ethoxylates as non-ionic surfactants due to their superb stability against hard water, pH-shock and electrolytes.
