SUBSTANCE: invention refers to the new particles of the basic aluminium salt containing the anion of the organic acid and having the following formula (I): M_a[Al_1-xM'_x]_bA_zB_y(OH)n·mH₂O (where M is at least one cation selected from the Na⁺, K⁺, NH₄ ⁺ and H₃O⁺; M' is at least one metal cation selected from the Cu²⁺, Zn²⁺, Ni²⁺, Zr⁴⁺, Fe²⁺, Fe³⁺ and Ti⁴⁺; A is at least one anion of the organic acid selected from the anions of oxalic, citric, malic, tartaric, glyceric, gallic and lactic acids; B is at least one anion of the inorganic acid selected from the sulphate (SO₄ ^2-), phosphate (PO₄ ^3-), and nitrate ions (NO₃ ^1-); and a, b, m, n, x, y and z meet the conditions 0.7≤a≤1.35; 2.7≤b≤3.3; 0≤m≤5; 4≤n≤7; 0≤x≤0.6; 1.7≤y≤2.4 and 0.001≤z≤0.5 respectively). The particles have the form of the grains, paired particles, rectangular parallelepipeds, disks (having the form of the Go stones), hexagonal plates, rice grains or cylinders with their diametre being constant. The invention refers also to the method of these particles preparation, to the additive to the polyethylene or polypropylene, to polymer resin containing these particles, to the polymer resin composition containing the additive with mass ratio additive/polyethylene or polypropylene (0.5-90):100, to the adsorbent consisting of these particles, to the colorant carrier and to the UV light absorber consisting of the particles of basic aluminium salt.

EFFECT: enhancing of the transparency and tensile strength.
