Specimens were prepared by compression molding with three various thicknesses and extrusion. These specimens were annealed at five various temperatures of -22, 5, 22, 40, and 60 \u00B0C during a time. The evolution of tensile properties was carried out on extrudates and the results were consequently compared with the evolution of injection-molded specimens. From this observation it was found that values of moduli in extrudates are remarkably higher than in the injection-molded specimens. This is a consequence of different morphological structure, which has direct impact on mechanical properties and the kinetics of the phase transformation in PB-1. It is evident that processing is a key parameter influencing mechanical properties and together with annealing temperature significantly influences the rate of the phase transformation of PB-1."@en . . . .
