Abstract
The regularities of colloidal particles formation in the volume of acetone and glycol SnCl2 solutions in presence of a number of stabilizing additives have been investigated. It was found that in relation to oxidation and hydrolysis of Sn (II) acetone and glycol solutions are much more stable than aqueous and alcohol solutions. The factors influencing their mediation activity in relation to the fixation of an inorganic nitrogen-phosphorus-containing flame retardant on polyester matrix have been established. It has been proven that the formation of numerous homogeneous colloidal particles with sizes not exceeding 20-25 nm in the volume of SnCl2 solutions is a necessary condition for achieving a high mediating effect on fixing a fire retardant on a polyester surface.
