The expected variation of nuclear fissilities throughout the periodic table is examined by considering the competition between fission and neutron and proton emission during the deexcitation of an excited compound nucleus.
Fission barriers and particle binding energies, upon which the competition depends, are evaluated on the basis of the liquid-drop model; nuclear level density parameters are taken proportional to the atomic mass number. The examination indicates that, contrary to what has been supposed previously, the fissilities of elements lighter than about silver should increase with decreasing Z2/A.

## Abstract Summary: An advanced isoconversional method has been applied to determine the effective activation energies (__E__) for the glass transition in polystyrene (PS), poly(ethylene terephthalate) (PET), and boron oxide (B~2~O~3~). The values of __E__ decrease from 280 to 120 kJโยทโmol^โ1^ in
