The ring-opening polymerization of cyclosiloxanes in the presence of bis ([alpha], [omega]-aminopropyl)-1,3-tetramethyldisiloxane
The ring-opening polymerization of octamethylcyclotetrasiloxane, D₄ , in the presence of bis(α,ω-aminopropyl)-1,3-tetramethyldisiloxane using potassium siloxanolate and tetramethylammonium siloxanolate catalysts has been investigated. The use of reversed-phase high performance liquid chromatography …
