Polydadmac, an acronym for polydiallyldimethylammonium chloride, is a linear and highly charged cationic polymer that plays a pivotal role in modern water treatment technologies. Its unique chemical structure, featuring quaternary ammonium groups on each repeating unit, gives it a permanent positive charge irrespective of pH, making it an extraordinarily versatile coagulant and flocculant. In the complex landscape of water pollution, where natural organic matter, industrial dyes, heavy metals, and colloidal particulates dominate, Polydadmac demonstrates remarkable efficacy. It works primarily through charge neutralization, compressing the electrical double layer of negatively charged contaminants, and inter-particle bridging, thereby promoting rapid aggregation into settleable flocs.
