Synthesis of polyacrylonitrile via ARGET ATRP using CCl 4 as initiator
Activators regenerated by electron transfer (ARGET) for atom transfer radical polymerization (ATRP) of acrylonitrile (AN) was investigated using carbon tetrachloride (CCl 4 ) as initiator, ferric trichloride anhydracs (FeCl 3 )/iminodiacetic acid (IDA) as catalyst system, L ‐ascorbic acid (VC) as re...

Zusammenfassung: | Activators regenerated by electron transfer (ARGET) for atom transfer radical polymerization (ATRP) of acrylonitrile (AN) was investigated using carbon tetrachloride (CCl
4
) as initiator, ferric trichloride anhydracs (FeCl
3
)/iminodiacetic acid (IDA) as catalyst system,
L
‐ascorbic acid (VC) as reducing agent, and
N,N
‐dimethylformamide (DMF) as solvent. Kinetic data of polymerization demonstrated the features of living/controlled free‐radical polymerization. The conversion of AN increased with the increasing concentration of CCl

]/[IDA] catalyst system and VC. The molecular weight decreased with the increasing concentration of CCl

, [FeCl

]/[IDA] catalyst system and VC. The value of polydispersity index (PDI) increased with the increasing concentration of [FeCl
3
]/[IDA] catalyst system and VC, while the value of PDI decreased first and then increased with the increasing concentration of CCl
4
and IDA.
