摘要：

The phase behaviour in neutral and acid aqueous solution is reported for two poly(oxyethylene)/poly(oxybutylene)/poly(oxyethylene) (EBE) triblock copolymers, of composition E(33)B(10)E(33) and E(43)B(14)E(43). Micellar solutions of both copolymers were utilised for templated-silica synthesis under acidic conditions. Calcination of the silica products gave mesoporous materials. The E(33)B(10)E(33)-templated silica exhibited a spherical morphology, whilst the E(43)B(14)E(43)-templated silica comprised irregularly shaped particles.
