An Environmentally Friendly Inverse Microemulsion Method to Synthesize Polyacrylamide
Polyacrylamide (PAM) was prepared by a new method of inverse microemulsion polymerization, with (NH(4))(2)S(2)O(8)-Na(2)SO(3) as initiator and liquid paraffin/Span80-Op10/AM-H(2)O-NaAc as polymerization system in this paper. The effects of initiator dosage, emulsifier dosage, monomer concentration,...

Sumario: | Polyacrylamide (PAM) was prepared by a new method of inverse microemulsion polymerization, with (NH(4))(2)S(2)O(8)-Na(2)SO(3) as initiator and liquid paraffin/Span80-Op10/AM-H(2)O-NaAc as polymerization system in this paper. The effects of initiator dosage, emulsifier dosage, monomer concentration, oil–water ratio, and temperature on molecular weight, electrical conductivity, particle size distribution, and monomer conversion were studied as well. The results indicate that that the more stable Polyacrylamide (PAM) polymer was prepared under the conditions of initiator dosage of 0.4~0.5%, emulsifier dosage of 55~60%, temperature of 40~45 °C, hydrophile–lipophile balance (HLB) value of 8.0~8.2, and NaAc concentration of 3%. |
