- Abstract
- Wide-Angle X-ray Diffraction (WAXD) and
Small-Angle X-ray Scattering analyses were carried out to
evaluate the evolution of the crystalline and supermolecular
structure of poly(ethylene terephthalate) (PET) blended with
poly(trimethylene terephthalate) (PTT). The conditions
adopted in preparing the PET/PTT 50/50 blend induce transesterification
between the polyesters; these reactions produce
a new molecular characteristics based on PET/PTT
copolymer that exhibits its own WAXD profile. The PET/
PTT 50/50 copolymers prepared by melt mixing of the
homopolymers for increasing times evidence spherulitic
morphology and an evolution of the crystalline structure in
terms of crystallinity and crystal dimensions. The periodicity
of the transesterificated samples is intermediate between
the long periods observed for pure PET and pure PTT. For
the PET/PTT 50/50 copolymers the value of periodicity and
lamellar thickness increase with the increasing of the processing
time. (literal)
