- W2367268781 abstract "It was found that yttrium tris(2,6-di-tert-butyl-4-methyl phenolate) could be an effective initiator for polymerization of acrylonitrile.The study of influence of solvent showed that DMF with high dielectric constant gave higher conversions(94%) at 50℃,3 h.The kinetics of acrylonitrile polymerization using Y(OAr)_3 in DMF was investigated by the weight method.The results indicated that the rate of polymerization showed a first order relationship with respect to both the monomer(AN) concentration and the initiator [Y(OAr)_3] concentration,respectively,and the overall activation energy of polymerization reaction was 22.1 kJ5mol -1 according to the Arrhenius equation. 13C-NMR studies showed that the PAN prepared had a syndiotactic triad (rr) content of 52%." @default.
