Yan‐Ning Sun, MA Xi-chen

Open publisher page 0 citations

Abstract

A natural high molecule modified starch cationic flocculent is synthesized with diallydimethyl ammonium chloride and acrylamide as raw material,using complex initiator and there-member polymerizing in aqueous solution.This paper describes the experiment study and results.Factors affecting the products' intrinsic viscosity,grafting percentage,monomer conversion,and cationic degree are detailed.They are as follows: monomer addition method,ration of starch and monomer,ratio of monomer,concentration of initiator,reaction time,and reaction temperature.
