Get Price- 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%).
- Does polymerization lead to a limited monomer conversion?
- However, this polymerization led to broad MWDs (Đ > 2.5, entry 2 in Table 1) with obvious tails in the size exclusion chromatography (SEC) traces (Figure S1), indicating that severe chain terminations occurred. This resulted in a limited monomer conversion, only 31.1% was reached in 75 min, and a poor control over the chain growth. Table 1.
