COMPATIBILIZATION OF IMMISCIBLE POLYMERS USING CARBON NANOTUBES Russian patent published in 2025 - IPC C01B32/158 C01B32/168 C01B32/194 

FIELD: chemistry.

SUBSTANCE: invention relates to multiphase polymer mixtures. Disclosed is a polymer mixture comprising at least two immiscible polymers and a carbon nanotube pulp, including entangled carbon nanotubes, characterized by that they have a diameter of about 10 nm to 100 nm and a length of about 0.1 mm to 10 mm, and also have two or more of the following characteristics: (i) a density of about 0.3 g/cm³ to 1.9 g/cm³, (ii) an aspect ratio of at least about 250,000, (iii) a breaking strain of about 1.8% to 7% and (iv) a surface area of about 100–300 m²/g. Invention also discloses a method of forming said polymer mixture, a granule containing said mixture, which is used for finishing or moulding, as well as articles made from said mixture.

EFFECT: disclosed polymer mixtures have improved impact resistance, modulus of elasticity and fire resistance.
