FIELD: chemistry. n SUBSTANCE: invention relates to a biodegradable thermoplastic composition. The composition contains polyethylene, wood flour and functional additives, such as concrete stone, polyvinyl alcohol, a compatibilising agent and nanoparticles. The compatibilising agent is primarily an ethylene and vinyl acetate copolymer and the nanoparticles are chemically deposited iron hydroxide or calcium sulphate nanoparticles. n EFFECT: use of cheap and readily available wood mechanical processing wastes, with high concentration thereof, as biodegradable material in the disclosed composition allows for normal use of articles in ordinary conditions, as well as the given rate of biodegradation in disposal conditions after use; wherein polyethylene in the composition can be used in form of manufacturing and/or household wastes. n 3 cl, 1 tbl |
