Miscibility and Characterization of Poly(viny butyral)/Poly(methyl methacrylate) Blends
E-mail:
The current work describes the interaction of poly(methyl methacrylate) (PMMA) with random copolymer poly(vinyl butyrals)(PVBs) at various hydroxyl levels of residual vinyl alcohol (VA) in the PVB. The DMTA, SEM, and physical property data showed that blends with a generally lower residual VA content evidenced compatibility, while a blend of PVB containing about 23 wt% VA with PMMA at a ratio of 80:20, respectively, was thermodynamically miscible. The miscibility parameter model proved useful in examining potential regions of compatibility/miscibility and indicated that dispersive-polar interactions were mainly responsible for the miscibility of the amorphous phases.
