โœฆ Synopsis

The great stabilizing effect of conjugated carbonyl groups upon radical anions is well known. We here report e.s.r. spectra of unsaturated esters, which illustrate the effects of cis-trans isomerism on e.s.r. spectra.

## Abstract In this work, we have calculated the thermodynamic parameters of the first steps of the free radical and anionic polymerizations of various unsaturated monomers, using ab initio methods of quantum chemistry. The enthalpies and entropies of polymerization were estimated assuming that the
