FIELD: chemistry.
SUBSTANCE: invention relates to a gaseous barrier layer in elastomer inflated objects, which contain gas, such as air, under pressure. In particular, the barrier layer can include a bus for preventing migration of oxygen and other gaseous components through the bus. The barrier layer is made from at least one elastomer, laminar mineral particles, which reduce permeability, reinforcing filler, cross-linking agent and from 1 to 50 wt pts terpenic hydrocarbon resin per 100 parts of elastomer. Glass transition temperature of the terpenic resin is almost 50°C higher and softening temperature is lower by almost 170°C.
EFFECT: improved manufacturability of the composition and improved permeability properties of the barrier layer.
