CHEMICKÁ MODIFIKACE POLY(3-HYDROXYBUTYRÁTU) Byla studována chemická modifikace poly(3-hydroxybutyrátu) spočívající v začlenění strukturních jednotek ε-kaprolaktonu do struktury polymeru. Modifikace byla prováděna polymerizací ε-kaprolaktonu v přítomnosti poly(3-hydroxybutyrátu) rozpuštěného v toluenu při 105°C. Pro porovnání byla též studována roztoková polymerizace ε-kaprolaktonu v toluenu. Byl studován vliv iniciátoru (2-ethylhexanoát cínatý, ethylmagnesiumbromid, tri(isopropoxid) hlinitý) na průběh obou typů polymerizace. Připravené materiály byly charakterizovány stanovením obsahu polymeru a viskozitně průměrné molární hmotnosti. Vybrané vzorky kopolymerů byly charakterizovány termickými metodami (TGA, DSC) a stanovením redukované viskozity. Poměr strukturních jednotek 3-hy…

Chemical modification of poly(3-hydroxybutyrate) A chemical modification of pol(3-hydroxybutyrate) based on incorporation of ε-caprolactone structural units into polymer backbone has been studied. The modification was carried out by polymerization of ε-caprolactone in the presence of poly(3-hydroxybutyrate) dissolved in toluene at 105°C. Solution polymerization of ε-caprolactone in toluene was considered as a reference. The influence of iniciator type (stannous octanoate, ethylmagnesium bromide and aluminium tri(isopropoxide)) on the both type of polymerization has been evaluated. Prepared materials were characterized by the determination of polymer yield and viscosity-average molar mass. Selected samples were characterizated by termal methods (TGA, DSC) and by the determinatio…
