El. Madruga et M. Fernandezgarcia, KINETIC-STUDY OF FREE-RADICAL COPOLYMERIZATION OF METHYL ACRYLATE ANDMETHYL-METHACRYLATE IN BENZENE, Macromolecular chemistry and physics, 197(4), 1996, pp. 1185-1191
The variation of copolymerization rate with composition obtained for t
he system methyl acrylate (1)/methyl methacrylate (2)/benzene/2,2'-azo
isobutyronitrile using standard techniques of polymerization rate meas
urements has been interpreted on the basis of a penultimate effect upo
n the propagation reaction, giving values of s(1) = 0.547 and s(2) = 1
.668 for the chain-end reactivity ratios.
