  • 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.
  • Why is RdRP of Am catalyzed by CuCl/CuCl 2 /bipyridine complex?
  • For example, RDRP of AM catalyzed by CuCl/CuCl 2 /bipyridine complex in water (H 2 O) suffered from the problem of the poorly controlled polymerization process with low Mw tailing, broad dispersity (Đ = ∼1.70), and limited monomer conversion (Conv. <38%).
  • What is response surface methodology (RSM)?
  • Box and Wilson established response surface methodology (RSM) as a sequential technique for chemical process engineering in the 1950s. It began to be employed in polymers and related sectors in the late 1990s [ 25, 26, 27, 28, 29 ]. RSM is an appropriate approach for simulating, designing, developing, and evaluating procedures.
  • How can RSM improve polymerization parameters?
  • Numerous researches have been conducted to improve polymerization parameters such as temperature, duration, and polymer content. In batch runs employing BBD, RSM was utilized to monitor and modify the catalyst activity and melt flow rate (MFR) during propylene slurry polymerization.
