The miscibility criteria of poly(isobutylene) (PIB) and poly(ether imide) (Ultem) were investigated at 30 oC in chloroform in dilute solutions by viscometric analysis. The intrinsic viscosity and viscometric parameters of this blend system were determined for several PIB/Ultem mixtures in compositions such as 80/20, 70/30, 60/40, 40/60, 20/80 in chloroform solutions. The miscibility criteria on the basis of the sign of Δb, Δb , Δ[η] , α and β which are the difference between their experimental and ideal values were calculated by applying theoretical equations. The data obtained from the viscometry studies showed that the prepared blends were immiscible in all the studied composition ranges at 30 oC. The miscibility of the mixtures was also studied by fourier transform infrared spectroscopy.

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.
