Abstract
Methylmethacrylate (MMA) can be initiated by charge transfer complexes (i) formed by the interaction of aliphatic amines and MMA and (ii) formed by the interaction of aliphatic amines and carbon tetrachloride in a solvent like N-N dimethylformamide (DMF), dimethyl sulphoxide (DMSO) or chloroform. This paper reports the polymerization of MMA by isopropylamine (IPA) in the presence of CCl 4 in DMSO at 30. The rate of polymerization, R p increases rapidly with CCl 4 up to a concentration of 0.25 mol l −1 but, for a higher concentration, it is practically independent of the CCl 4 concentration. R p is proportional to (IPA concentration) 1 2 and to power of (MMA concentration) 1.30 when [CCl 4] ⩾ [IPA]. The average rate constant, k, is 2.1 × 10 −6 l mol · 1 sec − 1.
