摘要: Atom transfer radical polymerization using activators generated by electron (AGET ATRP) of acrylonitrile (AN) initiated ethyl 2-bromoisobutyrate (EBiB) was approached for the first time in absence oxygen and presence air, a novel catalyst system based on SmBr3·6H2O/isophthalic acid complexes ascorbic (VC) as reducing agent. Both air proceeded well-controlled manner evidenced kinetic studies. Compared with oxygen, provided rather slow reaction rate showed better control molecular weight its distribution under same experimental conditions. The apparent activation energies were calculated to be 47.1 51.3 kJ·mol−1, respectively. A broad polydispersity index observed anisole ...
