The miscibility criteria of a poly (ether imide) (Ultem) and poly (methyl methacrylate) (PMMA) was investigated at 25 °C in chloroform in dilute solutions by viscometric analysis. The intrinsic viscosity and viscometric parameters of these blend systems were determined for several Ultem/PMMA mixtures in compositions such as 80/20, 60/40, 40/60, 20/80 in chloroform solutions. The miscibility criteria on the basis of the sign of viscometry, m Δb , m Δb , m Δb and m Δ[η] which are the difference between their experimental and ideal values were calculated by applying theoretical equations proposed by Krigbaum–Wall, Catsiff–Hewett and Garcia et al. The data obtained from the viscometry studies showed that the prepared blends were miscible in all the studied composition ranges at 25 °C. The miscibility of the polymers was confirmed by the results of differential scanning calorimetry (DSC) and fourier transform infrared spectroscopy (FT/IR ATR) measurements..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
