BIODESTRUCTIBLE POLYMER COMPOSITE MATERIAL BASED ON ARTIFICIAL LATEX AND BIO-FILLER

Abstract
The study aims to create biodegradable composite materials based on non-emulsion polymer latexes with natural fillers. The article provides an analysis of the current state of the issue on the methods of obtaining and the state of the market of biodegradable polymer materials. The results of research on the development of a method for obtaining biodegradable polymer materials based on 1,4-cis-polyisoprene non-emulsion polymer latexes are presented. The paper develops recipes for the obtaining of artificial latex of isoprene rubber, a latex composition based on it, and also experimentally determines such technological parameters as the concentration of coagulant, the dipping mode of porcelain molds, the drying temperature of latex gel and vulcanization of films. During research has been proved the ability of the created polymer composite products to biodegradation under the influ-ence of biotic factors. Stimulation of biodegradation processes occurs due to the natural fillers of wood flour and coffee oil cake introduced at the latex stage in the form of pre-prepared suspensions. The developed technology makes it possible to obtain, using the method of coagulant sedimentation, composite polymer thin-film materials with adjustable operating time, makes it possible to reduce the load on the environment after the disposal of used products by burying them into the soil at polygons. The obtained polymer composite materials can be used to ob-tain dipped articles, for example, gloves for household, pharmaceutical, and chemical purposes.
