The Effect of Beta Irradiation on the Structural Changes of Isotactic Polypropylene
Original language description
The electron β irradiation of the isotactic polypropylene (iPP) influenced the chemical structure because it caused mostly the crosslinking of the polymer chains beside the macromolecule degradation. This effect led to the corresponding changes of physical and mechanical properties (crystallinity, crystal size, melting and crystallization temperatures). The amount of β phase of iPP in the samples decreased with increasing dose of β irradiation and it was changing into the α phase and amorphous phase. After the irradiation the melting temperature decreased and the spherulitical structure was partially decomposed. The imbibition in Xylene proved, that the highest degree of crosslinking was in the samples irradiated by a dose 33 kGy which showed the highest increase of density, crystallinity, melting temperature and elastic modulus.
