摘要

Poly(vinyl methyl ether) (PVME) and poly(benzyl methacrylate) (PBzMA) were found to be miscible using differential scanning calorimetry (DSC), optical microscopy (OM), and infrared spectroscopy (FT-IR). Solvents and casting temperatures strongly affect the kinetics of the formation of blends and lead to different phase structures of the blends. The thermal transition behavior of the PVME/PBzMA blend suggests a marginal miscibility. Various scales of molecular aggregation might exist in the blends. According to FT-IR the intermolecular interactions are weak and not specific, which is in agreement with the glass transition behavior of the blends. Additionally, this study also shows that PVME is immiscible with any other polymethacrylate, such as poly(methyl methacrylate), poly(ethyl methacrylate), poly(propyl methacrylate), poly-(phenyl methacrylate), poly(cyclohexyl methacrylate), etc.
