  • Can oxidized polyacrylamide (PAAM) to initiate radical homopolymerization?
  • CAN oxidized AAm to initiate conventional radical homopolymerization at 50–60 °C, and viscosity-average molecular weight (MW) of polyacrylamide (PAAm) steadily increased with conversion because of the oxidation of amidyl N–H moieties of in-chain -AAm- units, but MW was in a range from 10 4 to 10 5.
  • What is copper-catalyzed controlled polymerization of acrylamide?
  • Copper-catalyzed controlled polymerization of acrylamide (AM) has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (MWD) or requires complex/multistep reaction procedures, due to the highly active nature of the AM radical and its side reactions.
  • What is the MW of can oxidized polyacrylamide (PAAM)?
  • CAN oxidized AAm to initiate conventional radical homopolymerization of AAm at 50–60℃, and MW of polyacrylamide (PAAm) steadily increased with the conversion, but MW was in a range from 10 4 to 10 5. CAN-AAm redox-initiated radical co-polymerization of DMAAm formed PAAm-co-PDMAAm with a MW from 10 5 to 10 6.
  • How are acrylamide based polymers prepared?
  • In general, AAm-based polymers are prepared by radical polymerization of acrylamide (AAm) initiated by proper redox-pairs under specific conditions to achieve tailor-designed structures and properties [ 1 ].
