NOVEL BIODEGRADABLE POLYMER COMPOSITION SUITABLE FOR PRODUCING BIODEGRADABLE PLASTIC, AND METHOD OF PREPARING SAID COMPOSITION Russian patent published in 2013 - IPC C08L23/02 C08L23/04 C08L23/10 C08L25/06 C08L27/06 C08L101/16 C08J3/22 C08L3/20 

FIELD: chemistry.

SUBSTANCE: polymer composition contains a mixture of (i) a polymer selected from polyethylene, polypropylene, polystyrene, polyvinyl chloride or a mixture thereof (ii) cellulose, (iii) ammonium nitrate, (iv) nutrients selected from blue-green algae and/or yeast, and (v) water. This composition can be mixed with a pure base polymer to obtain a polymer master batch. The master batch of the composition can be mixed with a pure base polymer which is suitable for obtaining products which are biodegradable. Described also is a method of preparing a biodegradable polymer composition, a method of preparing a master batch of the biodegradable polymer composition.

EFFECT: biodegradation of the composition within 6 to 36 months, environmental safety, preparation of the biodegradable composition does not require special equipment.
