## Abstract Nonbonded interaction energies have been calculated for various conformations of the diester giving explicit consideration to the lone‐pair electrons. As suspected from an earlier calculation on the dipeptide, such inclusion of the lone‐pair effect leads to significant differences in th

The effects of physical aging, degree of crystallinity, and orientation of poly(1actic acid) (PLA) were studied using differential scanning calorimetry (DSC) and wide angle X-ray scattering (WAXS). The samples of PLA with 96% [L] and 4% [ D ] contents were prepared by injection molding. The physical

Physical aging of films of poly(ether ether ketone) kept for 2 months at 120ЊC was studied. The extent of aging was evaluated with different techniques. Aged samples show different thermal behavior and exhibit different mechanical, transport, and viscoelastic properties. An attempt was made to estab

Physical aging of poly(aryl ether ether ketone ketone) (PEEKK) has been investigated. Heat flow responses were measured after annealing the amorphous samples obtained by quenching the melt into an ice-water bath close to, but below, the glass transition temperature. The extent of aging is related to
