説明
A well-defined polymeric silane coupling agent, 3-(triethoxysilyl)propyl-terminated polystyrene (TESiP-PS) was synthesized by reaction of polystyryllithium with (3-chloropropyl)triethoxysilane. The reaction is greatly affected by reaction conditions. The yield of TESiP-PS was quantitative in a benzene/tetrahydrofuran medium at 0°C, whereas it was as low as 5% in benzene at room temperature. TESiP-PS obtained under the former conditions has 95% functionality and a monodispersity of 1.05. Condensation of TESiP-PS proceeds quantitatively in the presence of either base or acid catalyst. This result is different from that for triethoxysilyl-terminated polystyrene (TESi-PS), which undergoes complete cleavage in the presence of base catalysts. This sharp difference indicates that the introduction of a trimethylene group between the trimethoxysilyl group and polystyrene effectively suppressed the cleavage reaction.
