Abstract:
... By using an aqueous H₂O₂ solution and the reaction-controlled phase-transfer catalyst CPC-PW₄O₁₆, polybutadiene (PBD) was epoxidized quantitatively and efficiently up to an epoxy ratio of 20 mol %. During the epoxidation, the catalyst first interacted with H₂O₂ to generate an amphiphilic intermediate, which made the reaction mixture become a two-phase emulsion. The epoxidation of PBD occurred in t ...

Abstract:
... Small clusters of spherical colloids that mimic real molecules, so-called colloidal molecules, hold great promise as building blocks in bottom-up routes to new materials. However, their typical hard sphere nature has hampered their assembly into ordered structures, largely due to a lack of control in the interparticle interactions. To provide easy external control of the interactions, the present ...
