Grafting of styrene onto silica gel in the presence of γ‐methacryloxypropyl‐metyldiethoxy‐silane (R)

Abstract

The graft polymerization of styrene onto silica gel in the presence of the silicone modifier γ‐methacryloxypropyl‐methyldiethoxysilane has been investigated. The main peculiarity of the styrene polymerization on silica gel in the presence of this modifier is the screening of the silica gel surface by the grafted polystyrene a t the very beginning of the reaction. The mechanism of the increase of the rate of styrene polymerization on the silica gel surface in the presence of the modifier is discussed.
