According to the invention, the method for applying a polymer coating onto the surface of a solid filler comprises deposition of a complex organometallic catalyst, containing a compound of a transition metal and an organic compound of a metal of the second or third groups of the periodic system, on the surface of the solid filler and liquid- or gas-phase polymerization of olefins at a temperature of 50 DEG to 170 DEG C. and a pressure of 1 to 60 atm on said catalyst deposited on the surface of the solid filler. The deposition is carried out in two stages. The first stage is gas-phase deposition of the first component of the catalyst, i.e. a compound of a transition metal, on the surface of the solid filler. The second stage is gas- or liquid-phase deposition of the second component of the catalyst, i.e. an organic compound of a metal of the second or third group of the periodic system. Polymer coatings produced by this method are marked by a high quality and uniformity, as well as good adhesion to the surface of the solid filler. The coating density is 0.7 to 0.95 g/cm3. The thickness of such coatings can be varied within a broad range from a minimum of 7x10-3g/m2. The method according to the invention permits a considerable reduction in the consumption of the initial monomers and the catalyst; for example, the catalyst consumption can be reduced to a value as low as 0.001 to 0.1 percent of the weight of the filler on conversion to vanadium tetrachloride. The method is quite simple technologically.
