摘要：

Blends of poly(hydroxy ether of bisphenol-A) (phenoxy) and poly(methyl methacrylate) exhibit a different phase behaviour depending on the blending method. Additionally, both polymers present similar glass transition temperatures complicating the study of the phase behaviour by classical DSC methods. The problem has been resolved by using different experimental techniques (enthalpy relaxation, DMTA, CP-MAS NMR) which have confirmed the intrinsic miscibility of this blend. The influence of the poly(methyl methacrylate) tacticity in the miscibility of the blends has also been studied.
