Evolution of physical and mechanical properties during phase transformation in poly(1-butene)
Original language description
The work is focused on study of evolution of the physical and mechanical properties of poly(1-butene) (PB-1). This evolution was observed during the phase transformation from the metastable form II to the thermodynamically more stable form I. Three different commercially-available grades of PB-1 were used in this work; two homopolymers and one ethylene copolymer. Specimens were prepared by compression molding with three various thickness and by extrusion This specimens were annealed at five various temperatures of -22, 5, 22, 40, and 60 °C during a time. Content of the form I in specimens was calculated by wide angle X-ray scattering during the phase transformation. Physical properties were measured via density changes of specimens and changes of mechanical properties were measured via tensile testing. From density measurements, it is obvious that the different thicknesses of compression-molded specimens do not influence the evolution of rate of the phase transformation. Densities of c
