“…Qualitatively similar behavior is known in the paint industry (35,36) where the drying process appears to take place in two stages.In the first or "wet" stage, which occurs early in the process, evaporation is controlled by factors external to the film. In the second or "dry" stage, solvent diffusion in the film is controlling.…”

The observed variation of film thickness with spin speed (i~) in spin coating is summarized for resists, spin-on glasses (SOGs), and polyimides. While the thickness measurements of resists and SOGs show an ~ 1/2 dependence, the data for polyimides show a wide variation in speed dependence, from ~l-1 to gt-~/2. The possible non-newtonian nature of the fluid (modeled as a truncated power law) cannot explain this behavior since predictions indicate that non-newtonian effects are always accompanied by a variation in the thickness with radial position, a variation which has not been observed experimentally. However, the type of evaporation model used for the fluid can cause the thickness to vary with speed in the observed fashion. This suggests that the polyimide behavior is a result of differences in the evaporation rate of the solvent.

“…Residual solvent plasticizes poorly dried polymer, reducing its modulus and transition temperature. Even after extended drying, small concentrations of solvent may be retained in polymers (39). Figures 6 and 7 show the effect of inadequate drying on the shear storage modulus (G') and the loss modulus ( G " ) , respectively, of Kel-F 800/PMMA:25/75 blends.…”

An approach to high-density, high-modulus binders for explosives is to blend low-density, high-modulus polymers with high-density, low-modulus polymers. Improved properties, which these pairs theoretically should have, are discussed. Two attempts to achieve miscibility between a high-density fluoropolymer (Kel-F 800) and high-modulus thermoplastics (Lucite 130 and Phenoxy PKHJ) were unsuccessful. These blends are immiscible and their physical properties are additive or only slightly enhanced. Anelastic properties of the blends indicate phase separation by the presence of two glass transitions, one associated with each phase.

“…Thus, for toxicological and physicochemical reasons, drug manufacturers are increasingly required to monitor and limit the presence of RS in their products. 8 RS determination using different techniques is repeatedly found in the literature; briey, nonspecic techniques, such as the loss on drying technique, 9,10 or little advanced techniques, such as thermogravimetric techniques 11 and determination of chlorine content for chlorinated solvents. 12,13 More sophisticated techniques, such as infrared spectroscopy 14 and Fourier transform infrared spectrometry 15 were used to determine residual tetrahydrofuran, dichloroethane and methylene chloride in polymer samples.…”
