Abstract
Urgency of the studies aimed at the development of ecologically safe, naturally biodegradable polymer materials including biopolymers of natural origin — polyhydroxyalkanoates — is demonstrated. Short– and medium–chain samples of polyhydroxyalkanoates of the new chemical structure with different combinations of the fractions of 3– and 4–hydroxybutyrate or 3–hydroxyhexanoate were obtained. The physicochemical and mechanical properties of copolymer samples of polyhydroxyalkanoates were studies.
