摘要: Propagation rate constants have been determined at two temperatures (298 K and 323 K) for the copolymerizations of styrene (STY) with methyl acrylate (MA) STY n-butyl (BA) over a range monomer feed compositions. A pulsed UV laser was used as an initiation source gel permeation chromatography (GPC) utilized to analyse products. None conformed Mayo-Lewis model, respect their propagation constants. The results were interpreted on basis penultimate effect reaction. In addition, Mark-Houwink poly(MA) poly(BA) in tetrahydrofuran (THF) 298 K. These are given (K(dm3 kg- I), a): 7.88 x 10- ', 0.885 8.57 lo', 0.865 respectively.
