POLYMER DECOMPOSITION INITIATING UNIVERSAL ADDITIVE AND METHOD OF PRODUCING SAID ADDITIVE Russian patent published in 2012 - IPC C08L3/02 C08L89/00 C08L101/16 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical and food industry, particularly to production of biodegradable plastic materials and can be used to make moulded or film articles for various purposes, including food purposes. In the method of producing a universal additive which initiates polymer decomposition, exclusively consisting of natural material which includes a matrix, natural polysaccharides, binder, a heat stabiliser and a culture medium, involving mixing said components in a heated mixer at temperature 40-70°C and further granulation or pelletisation of the obtained mixture, the novelty lies in that the matrix contained in the additive is edible paraffin (food additive E905), oxidised polyethylene wax (food additive E914), the natural polysaccharide is starch, the binder is collagen-containing products (gelatin, belkozin, hide glue etc), the heat stabiliser is modified starch THERMTEX and the culture medium is phospholipids.

EFFECT: invention increases biodegradability of the compositions and improves heat stabilisation properties thereof, enables to control the biodegradation duration of the compositions and water-absorption of the material and improves rheological properties of the compositions.
