The specific rate constants for formation of methyl, aminomethyl, hydroxymethyl and cyanomethyl free radicals were cakulated using the transition state theory. The activation energies were calculated using the UHF in the MNDQ level with complete geometry optimization. Force field calculations were p

Five polypropylene films were prepared having different crystallinity and morphology, the latter having been modified by stretching. They were colored with azo dyes XC6H4N=N&H4N(C,H5), (where X=H, OCH,, CN, and NO,). The kinetics of the thermal cis-trans isomerization of these dyes has been studied

The thermal cis-trans isomerization of azo dyes XC6H4N=NC6H4N(C2H5)2 (where X is H, OCH3, CN, and NOz) in poly(ethy1ene terephthalate) matrices, below the glass transition temperature, and in dibutylphthalate solutions has been studied kinetically in the temperature range 20-60Β°C.
