“…[5] While the former observed a rapid increase in rate of polymerization up to a limiting concentration of CCl 4 and independent beyond that, the latter reported different dependency of monomer concentration when [C]/[A] that is, the ratio of concentration of CCl 4 to amine is ≤1 and ≥1. These authors reported overall rate and average polymerization rate constants.…”

The charge transfer polymerization of methyl methacrylate (MMA) in presence of n-butyl amine (nBA) and carbon tetrachloride (CCl 4 ) with dimethyl sulfoxide (DMSO) as solvent was experimentally investigated. The variables include concentrations of MMA, nBA, CCl 4 , DMSO and reaction temperature. The effect of these variables on monomer conversion, number and weight average molecular weights is discussed. A reaction mechanism is proposed and overall kinetics, propagation, chain transfer and termination constants are evaluated. A mathematical model is proposed for estimating monomer conversion, number and weight average molecular weights. The proposed model is validated using the kinetic constants and compared satisfactorily with experimental data of the present study.  2009

“…These mechanisms are (1) the interaction20 of amine and CCl 4 under the conditions [CCl 4 ]/[Amine] ≤ 1 and (2) the interaction21 of amine and MMA under the conditions [CCl 4 ]/[Amine] ≥ 1. Dass and coworkers22, 23 and Dwivedi et al24 presented experimental evidence that both types of mechanisms are possible. Thus, the charge‐transfer complex polymerization of MMA initiated by amine/amino alcohols and CCl 4 has been investigated with these mechanisms in detail by many investigators 25–35…”

We studied the kinetics and mechanism of the charge‐transfer polymerization of methyl methacrylate (MMA) initiated with n‐butyl amine (BA) and carbon tetrachloride (CCl4) catalyzed by palladium dichloride (PdCl2 or PdII) in a dimethyl sulfoxide medium by using a dilatometric technique at 60°C. The rate of polymerization (Rp) was a function of [MMA], [BA], [CCl4], and [PdII]. The kinetic data indicated a mechanism involving the possible participation of the charge‐transfer complex formed between the {BA–PdII} complex and CCl4 or monomer in the polymerization of MMA. In the absence of either CCl4 or BA, no polymerization of MMA was observed under these experimental conditions. Rp was inhibited by hydroquinone; this suggested a free‐radical initiation. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

ABSTRACT:The charge transfer initiated polymerization of acrylonitrile by 2,4-dinitrophenylhydrazine (DNPH) and Cu2+ in the presence of carbon tetrahalide was studied in dimethyl sulphoxide at 60°C. The rate of polymerization became maximum when the mol ratio of [DNPH] EXPERIMENTAL MaterialsOur previous works 1 -7 reveal that compounds containing a donor nitrogen atom can play a significant role in initiation and propagation steps of charge transfer (CT) initiated polymerization. The CT initiated polymerization of vinyl monomers like methyl methacrylate (MMA), 1 -7 2-vinylpyridine, 8 etc. has already been reported. It was found that metal ions have profound effect on the rate of CT initiated polymerization. It should be worthwhile to follow the rate of polymerization of acrylonitrile (AN) in the presence of metal ions and carbon tetrahalide for elucidating this complex but important problem. The present communication reports the polymerization of AN in the presence of 2,4-dinitrophenylhydrazine (DNPH) and tetrakis dimethyl sulphoxide copper(II) perchlorate, [Cu(DMS0) 4 ] (Cl0 4 )z, A with carbon tetrahalides in dimethyl sulphoxide (DMSO) at 60°C. AN, 9 DMS0 5 and carbon tetrachloride 5 were purified as reported in the literature. Carbon tetrabromide and DNPH were used without further purification.The complex, A, was prepared as before. 5 PolymerizationExperiments were done in a three limbed vessel and the rates of polymerization were measured dilatometrically in the usual way. 10
