Аннотация

Mechanical energy released during stirred grinding promotes the polymerization reactions of styrene monomers on calcium carbonate and those of polystyrene on titanium dioxide surfaces and makes the surface modification by polymer grafting more efficient and with less initiating agent. Polymer grafting modification activated by mechanochemical effects improves the compatibility of calcium carbonate filler with the polymer matrix and the fluidity of alkyd varnish with modified titanium dioxide as the paint material. The process of polymer grafting modification activated by mechanochemical action and the changes of application properties of materials filled with modified powders are described, the interactions between the modifying agents and the surface of the powders is discussed.
