POLYETHYLENETEREPHTHALATE-BASED POLYMER COMPOSITION Russian patent published in 2015 - IPC C08K13/02 C08L67/00 

FIELD: chemistry.

SUBSTANCE: invention relates to polyethyleneterephthalate-based composite materials, used for manufacturing one-layered containers in form of bottles, possessing increased barrier properties. Polyethyleneterephthalate-based polymer composition, applied as composite material, contains boron anhydride and superconcentrate, used as modifier and consisting of polyamide-6 and organoclay. Organoclay represents product of montmorillonite modification with cation-exchange capacity 95 mg eq/100 g of clay, with caprolactam.

EFFECT: composite material possesses higher barrier properties, such as oxygen permeability and vapour permeability.
