FIELD: modified polymeric material with particles of boehmite, boehmite material and method for formation of extruded product.
SUBSTANCE: the modified polymeric material contains a polymeric substructure and particles of boehmite. The particles of boehmite represent needle-shaped particles having a shape factor making up at least about 3:1, where the shape factor represents a ratio of the largest length of the particle and its largest width, the largest size of the boehmite particles is within 50 to 2000 nm. The method of formation of the extruded product consists in the fact that first is prepared the modified polymeric material from a polymeric substructure and particles of boehmite. Then the material is extruded, the boehmite particles being dispersed in the extruded product.
EFFECT: improved modulus of elasticity, flexural modulus, safekeeping modulus, tensile strength, deformation temperature of extruded product.
