cze	Syntéza hvězdicovitých polymerů pro polyurethanové nátery pomocí iontové polymerace	Hviezdicovité polyméry boli pripravené ionovou polymerizáciou. Ako jadro hviezdy, bol použitý napr. trimetylol propán (TMP), pentaerytritol (PETP), dipentaerytritol (DPETP) a ramená boli syntetizivané z ε-kaprolaktámu a laktidu v roznych pomeroch. Nátery založené na TMP majú proti šmykové vlastnosti, vysoký lesk ale nižšiu tvrdosť. Pre porovnanie, nátery založene na PETP a DPETP majú vysokú tvrdosť, ale žiadne protišmykové vlastnosti.	iontová polymerace; polyuretanové nátěry
eng	Synthesis of star polymers applicable as filler for polyurethane coatings by ionic polymerization	Star polymers were prepared by ionic polymerization. As the star core polyols served e.g.: trimethylol propane (TMP), pentaerythrythol (PETP) and dipentaerythrythol (DPETP) and the star arms were built up from ε-caprolactame, lactide in different ratios of both components. Coatings based on TMP have often anti-slip properties high gloss but lower hardness. On the contrary, coatings based on PETP and DPETP have high hardness, but no anti-slip properties.	ionic polymerization; polyurethane Coatings
