Methods for the Preparation of Modified Polyorganosiloxanes (A Review)

Abstract

The review presents the main methods for the preparation of modified polyorganosiloxanes (POS) containing amino groups. Modified POS are the most important functional compounds for the synthesis of polyimide and polysiloxane copolymers used as a material for polymeric electrolytic membranes (PEM) of fuel cells (FC). The reactions of cationic and anionic polymerization, hydrosilylation, condensation of chlorosilanes are considered. The main advantages and disadvantages of these methods are discussed.
