Heterofunctional Condensation of 4,6-bis(n-aminophenyl)pyrimidine with α,ω)-bis(diethylamino- and α,ω-bis(β-carboxylethyl)diorganosiloxanes

Abstract Copolymers containing siloxane fragments and aromatic heterocycles in their main chains of macro-molecules have been synthesized. Heterofunctional condensation of 4,6-bis(n-aminophenyl)pyrimidine with α,ω-(diethylamine)- and α,ω-bis(β-carboxylethyl)diorganosiloxanes was conducted at 1:1 molar ratio of initial components at 150–180°C. Thermogravimetric characteristics of the synthesized thermally stable copolymers have been investigated.
