    We explore the application potential of 4,4´-bis–(4´-hydroxyphenyl)pentanoic acid (BHPPA) based hyperbranched polyesters for coatings by studying the kinetics and build-up of polymer network formation from BHPPA and polyisocyanates.

    Je popsána příprava a možnosti aplikace v nátěrových systémech nového hypervětveného polymeru na bázi 4,4´-bis–(4´-hydroxyfenyl)pentanové kyseliny. Byly studovány kinetické parametry síťovací reakce s polyisokyanáty a vlastnosti sítí.
