The miscibility of poly(ether imide) (Ultem) and liquid crystal 4-[(2S)-2-methylbutoxy]-N-[[4-[(5,5,6,6,7,7,8,8,9,9,10,10,10- tridecafluorodecyl)oxy]phenyl] methylene] benzenamine (MTOPMB) were investigated at 30 oC in dilute chloroform solutions by viscometric analysis. The intrinsic viscosity and interaction parameters were determined for individual components and binary Ultem/MTOPMB mixtures in compositions such as 80/20, 60/40, 40/60 and 20/80 (w/w) in chloroform solutions. The miscibility criteria on the basis of the sign of m Δb , m Δb , m Δb and m Δ[η] which are the difference between their experimental and ideal values were used in viscometric analysis. The data suggested that the studied binary mixtures were immiscible except the one of Ultem/MTOPMB: 80/20 (w/w). The miscibility of the mixtures was also studied by differential scanning calorimetry (DSC) and polarised light optical microscopy (POM)..

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.
