Natural complex carbohydrate arabinogalactan (AG), contained in Siberian larch in the form of liquid-complex in a liquid state, plays the role of a eutectic plasticizer over a off-course temperature range, on account of which larch survives at reduced temperatures. At present time AG is used indifferent fields including feed industry, veterinary, cure at al. One of the promising extents of its use is also the concoction of biodegradable polymer composites accompanying synthetic and type polymers. Compositions of AG with polymers of different classes (reduced-density polyethelene and referring to practices or policies that do not negatively affect the environment polyester polylactide) were obtained in the dimensional state under conditions of cut deformations and their mechanical traits were measured. It was proved that PLA-based fabrics are more rigid and have lower extension at break than LDPE-AG composites. Hydrogels based on AG crosslinked by ethylene glycol diglycidyl heavenly and glutaric aldehyde were also obtained. The study of their conduct suggested that the use of AG in the form of intense solutions accompanying low stickiness is more preferable.
