摘要：

The miscibility of poly(styrene-co-vinylphenol) (MPS) containing 1%, 2%, and 4.4% vinylphenol monomer units with poly(n-butyl methacrylate) (PnBMA) was studied with13C solid-state NMR complemented with DSC, FTIR, and cloud point measurements. Results indicate that the number of vinylphenol monomer units determines the domain size of these blends. The 4.4% MPS/PnBMA blend exhibits a single Tg. The limit of miscibility of this blend calculated from the NMR experiment indicates a scale of homogeneity corresponding to a T1ρH value of ~8 ms. © 1990, American Chemical Society.
