Sm. Deng et Fm. Meng, COPOLYMERIZATION OF ACRYLAMIDE WITH ACRYLONITRILE BY USING AMMONIUM PERSULFATE-N,N,N',N'-TETRAMETHYL ETHYLENEDIAMINE IN AQUEOUS-SOLUTION, Journal of macromolecular science. Pure and applied chemistry, A31(9), 1994, pp. 1289-1301
Studies were conducted on the copolymerization of acrylamide (AM) with
acrylonitrile (AN) by utilizing ammonium persulfate-N,N,-N',N'-tetram
ethyl ethylenediamine (APS-TMEDA) system as initiator in aqueous solut
ion. The copolymerization rate equation was established as R(p) is-pro
portional-to [APS]0.38[TMEDA]0.28[AM]0.91[AN]0.32 The reactivity ratio
s were determined by both of the Fineman-Ross and Kelen-Tudos methods,
and the values of r1 (AM) and r2 (AN) were determined to be r1 = 0.73
8 and r2 = 0.050. The apparent activation energy (E(a)) of the copolym
erization was calculated to be 25.03 kJ/mol.
