Effects of diffusion‐controlled reactions on atom‐transfer radical polymerization

Abstract A kinetic model incorporating effects of diffusion‐controlled reactions on atom‐transfer radical polymerization (ATRP) was developed. The reactions considered to be diffusion‐controlled are monomer propagation, bimolecular radical termination, chain transfer between propagating radical and catalyst, and transfer to small molecules. Model predictions indicate that a diffusion‐controlled propagation reduces the “living” behavior of the …
