Abstract
Blends of poly(hydroxy ether of bisphenol-A) (phenoxy) and poly(methyl methacrylate) exhibit a different phase behaviour depending on the bl ending method. Additionally, both polymers present similar glass trans ition temperatures complicating the study of the phase behaviour by cl assical 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 b lends has also been studied.
