Quaternary ammonium amphoteric polyacrylamide was synthesized by inverse micro emulsion.The retention,drainage performance and strength of amphoteric polyacrylamide were tested.The results show that when the dosage is 0.5%,the best performance in retention,drainage and strengthening can be obtained with the tensile index increased by 11.37%,tear index increased by 18.52%,retention rate increased by 7.66%,meanwhile the beating degree decreased by 12.9%.
