Quat 188 is an aqueous solution of N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride. The reaction of Quat 188 with select natural and synthetic polymers results in a cationically charged polymer. It is this interaction between the positively charged nitrogen and the many negatively charged materials that make Quat 188 modified products suitable as dry strength additives for paper, retention aids, flocculants, electroconductive resins, asphalt emulsifiers, emollients and various surfactant applications. Introducing Quat 188 into polymeric systems imparts three important characteristics: Increased Cationic Polarity: Cationic groups improve adhesion to polar substrates。 Increased Affinity for Anionic Materials: Polymers modified with Quat 188 have pendant cationic groups and will associate with materials containing negative counter ions, such as carboxyl, sulfonate, and many other negatively charged substrates. Increased Hygroscopicity: Polymers with cationic groups display increased water solubility as a result of the highly water soluble quaternary ammonium group. Polymers generally not soluble with water can thus be given some degree of water solubility.
