摘要

This work study influence of high-pressure crystallization on two homopolymers of poly(l-butene) (PB-1). Samples were non-isothermally crystalized under pressure range from 20 to 200MPa using a pvT 100 device. Obtained specimens were analyzed by using wide-angle X-Ray scattering (WAXS), differential scanning calorimetry (DSC) and polarized light microscopy (PLM). Significant impact of the pressure of crystallization on the phase I' and phase I appearance was observed.
