In general, the oxygen permeation in a semi-crystalline polymer
like PBS is primarily a function of the amorphous phase, while the
crystalline section is regularly assumed to be impermeable [29,30].
To confirm this structure-property relation, it is necessary to
observe the change in crystallization of the PBS/thymol blends.
Fig. 2 illustrates the heating and cooling thermograms of neat PBS
and PBS/thymol blends. The data of the crystallization temperature
(Tc), crystallization enthalpy (DHc), melting temperature (Tm),
enthalpy of melting (DHm) and degree of crystallinity (Xc) for the
neat PBS and PBS/thymol blends were indicated in Table 3. As
shown in Fig. 2(a), blending thymol to PBS decreased both Tc and
DHc compared to that of neat PBS. Tc reached the minimum value of
82.06 C when thymol was added at 10 wt%.
