Abstract
High molecular weight water-soluble topologically structured copolymers of acrylamide (AMD) and 2-(acryloyloxy)ethyltrimethylammonium chloride (AETAC) were synthesized by inverse emulsion polymerization process. Copolymers with various structures were attained by introducing appropriate amounts of branching and chain-transfer agent in the monomer feed. Polymer structure was characterized by solution rheological properties comprising the measurements of the viscosity of a 0.2% polymer solution in de-ionized water (Bulk Viscosity, BV) and the viscosity of a 0.1% polymer solution in 1.0 N NaCl (Standard Viscosity, SV). The synthesized polymers were then subject to flocculation test with several types of sludge. De-watering rate, filtrate turbidity, and percent cake solids were used to ascertain the efficiency of flocculation. It was found that the polymer with a high BV and a low SV had exceptional performance on certain types of sludges. A statistically designed experiment was conducted to reveal the quantitative relationships between the structure parameters (BV and SV) and the performance characteristics.
