摘要
Present work study the effect of high-pressure crystallization on morphology and thermal behavior of two different homopolymers of isotactic poly(1-butene). Both materials were non-isothermally crystallized under pressure in range from 20 to 200 MPa using a pvT 100 apparatus and thus prepared samples were investigated using differential scanning calorimetry and polarized light microscopy. Results showed significant effect of pressure on formation of metastable phases I' and II with respect to material properties on thermal behavior and morphology in isotactic poly(1-butene)
