| Abstract: | The PEO-grafted cationic polyacrylamide microparticles were synthesized via inverse microemulsion tetrapolymerization of acrylamide(AM), acryloyloxyethyl trimethylammonium chloride(ADAMQUAT), PEO-macromonomer(PEO-1000) and N,N′ -methylenebisacrylamide(Bis).The structure and properties of microparticle retention aids were studied.The microparticle could link with pulp fibre through ionic bond and hydrogen bond, from which excellent retention effect of copolymer initiated. |
