Abstract

Przedmiotem zgłoszenia jest kompozycja polimerowa na bazie polihydroksymaślanu, o kontrolowanej odporności na degradację i zmieniająca barwę podczas starzenia, która zawiera, oprócz polimeru, substancję przeciwstarzeniową i powodującą zmianę barwy kompozycji podczas starzenia w postaci ekstraktu z konopi siewnej w ilości 1,5 - 3,0 części wagowych na 100 części wagowych polimeru, przy czym kompozycja zawiera ekstrakt z konopi siewnej uzyskany metodą ekstrakcji nadkrytycznym CO2 jako rozpuszczalnikiem.The subject of the application is a polymer composition based on polyhydroxybutyrate, with controlled resistance to degradation and changing color during aging, which contains, in addition to the polymer, an anti-aging substance and a substance causing a change in the color of the composition during aging in the form of hemp extract in an amount of 1.5 - 3.0 parts by weight per 100 parts by weight of the polymer, wherein the composition contains hemp extract obtained by extraction with supercritical CO2 as a solvent.
