✦ Synopsis

The dependence of the fold period in poly(ethy1ene terephthalate) (PET) crystals on overcooling was investigated by the small-angle x-ray diffraction met,hod, for samples crystallized at 150' to 260°C. The equilibrium melting point T,, determined simultaneously, was 278" f 2°C. Using t,hese results, the surface free energy ue was calculated.

## Abstract **Summary:** Poly(ethylene 2,6‐naphthalate) (PEN) can crystallize either from the glassy state or from the melt state. When crystallized from the glassy state, the sample was quenched from the melt in liquid nitrogen and then annealed at certain crystallization temperatures. When crysta

## Abstract **Summary:** Analysis was made of the crystallization of the PET blocks in PET/PC copolymers as a function of the block length, varying from $\overline M \_{\rm n}$ = 5300 to 17100 g · mol^−1^ (__X__~n PET~ = 28–89, PET monomeric sequences). Analysis was also made of a series of PET hom
