THERMOPLASTIC MATERIAL CONTAINING NANOMETRIC LAYERED COMPOUNDS Russian patent published in 2008 - IPC C08K3/32 C08J5/18 B65D65/38 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention pertains to a mixture, the method of obtaining it, method of obtaining the product made from the mixture, and to products in form of layers of sheet material, hollow or solid pipes, and pipe or reservoir bottles. The mixture contains at least one thermoplastic matrix and particles based on a phosphate of zirconium, titanium, cerium and/or silicon. In that case, at least 50% of the above mentioned particles are in the form of nano-metric layered compounds, with a form factor less than or equal to 100. The mixture can be obtained through different methods. One alternative involves mixing the particles based on a phosphate of zirconium, titanium, cerium and/or silicon in the form of nanometric layered compounds with monomers and/or oligomers of a thermoplastic matrix before or during the polymerisation stage. The thermoplastic matrix is then polymerised. In another alternative, the above mentioned particles in the form of nanometric layered compounds are mixed with the thermoplastic matrix, and when necessary, the obtained mixture is mixed with at least one thermoplastic matrix. The product is made using an extrusion or moulding device.

EFFECT: obtaining of a mixture with good mechanical and barrier properties.
