Study on Synthesis and Application of Salt-Resisting polymer of Acrylic acid-Acrylamide
Shen Yan · Liaoning Chemical Industry · 2004
A salt-resisting polymer PAA was synthesized from the sodium salt of acrylic acid with acrylamide as comonomer,K 2S 2O 8 as initator,N,N-methylenebisacrylamide as crosslinking agent,by orthogonal design and the step-by-step temperature-rising.The optimum polymerization conditions were obtained: T=50 ℃ (2 h)~65 ℃(3 h),n AM∶n AA =1∶11,=90 %~95 %,=0.3 %,=30 %~35 %,=0.025 %~0.03 %. In addition,the PAA was applied well in chlorine dioxide absorbed in carrier.
