dc.description.abstract	Vliv UV záření na beta-nukleovaný vstřikovaný polypropylen (b-PP) byl studován na několika strukturních úrovních. Komerčně dotupný polypropylen byl modifikován 0,03 hm.% beta nukleantu. B-PP vzorky byly vstříknuty při procesních parametrech, kdy pouze teplota formy byla měněna. Bylo zjištěno, že vzorky mají slupka-jádro strukturu, která je silně ovlivněna teplotou formy. Tato stuktura pak ovlivnila degradabilitu vzorků, jak ukázala rentgenografie, mikroskopie a mikro-infračervená spektroskopie.	cs
dc.description.abstract	The effects of UV irradiation on P-nucleated injection-moulded polypropylenes (beta-iPP) have been Studied at several structural levels. Commercially available isotactic polypropylene was modified by 0.03 wt.% beta-nuclcating agent based on N,N'-dicyclohexylnaphtlialene-2,6-dicarboxamide. beta-iPP specimens were injection-moulded using a processing set-LIP in which only mould temperature was varied. It was found that specimens consisted of a skin-core structure, which was strongly influenced by varying mould temperatures. The structural development consequently affected the specimen degradability as shown by wide-angle X-ray scattering, light microscopy and micro-infrared microscopy. (c) 2005 Elsevier Ltd.
