PolyDADMAC Introduction

Polydiallyldimethylammonium chloride (shortened polyDADMAC or polyDDA), also commonly polyquaternium-6, is an important polymer (polyelectrolyte), that can effectively concrete high-level-grimed water. PolyDADMAC is a chemical substance whose molecular formula is a strong cationic polyelectrolyte existing as a kind of colorless to a light yellow viscous liquid.
