Analysis of melting temperature and crystal thickness derived from the interface distribution function analysis of SAXS data reveals that for T a<190 °C the occurrence of two lamellar stack populations prevails whereas for samples annealed at Ta>190 °C a population of lamellar stacks with a unimodal thickness distribution emerges. The H and E-values exhibit a tendency to increase with the degree of crystallinity. The results support a correlation E/H∼20 in accordance with other previously reported data. The changes of microhardness with annealing temperature are discussed in terms of the crystallinity and crystalline lamellar thickness variation. Unusually high hardness values obtained for PET samples crystallized at Ta=190 °C are discussed in terms of the role of the rigid amorphous phase which offers for the hardness of amorphous layers constrained between lamellar stacks a value of Ha∼150 MPa. On the other hand, for Ta=240 °C the decreasing H-tendency could be connected with the chemical degradation of the material at high temperature. © 2005 Elsevier Ltd.
