Abstract

Polyangelicalactone-graft- polystyrene copolymers (PAL‑graft-PS) were obtained through cationic polymerization. The resulting copolymers were completely destroyed when incubated in gray forest soil over 28 weeks. Individual strains of fungi destroyed the copolymer partially within 13 weeks; the most active among the studied cultures was Leptographium sp. The biodegradation products of copolymers do not statistically have a toxic effect. The obtained results show that the modification of polystyrene (PS) with the impurities of polyangelicalactone (PAL) gives them biodegradation abilities and does not worsen the properties of the copolymers
