dc.description.abstract	The work compared the effect of α-nucleating/clarifying agent based on 1,3;2,4-bis(3,4-dimethylbenzylidene)sorbitol on the photodegradation in two polypropylenes (PP). One of them was nucleated directly by producer while the second in the laboratory. For comparison, neat PP was studied as well. The samples were irradiated by UV-light and then examined using several methods. The results showed that the addition of α-nucleating agent influenced only slightly the process of photodegradation. However, significant differences in structure among the materials were observed.	en
