Spray drying has a wide variety of applications from production of dried milk to pharmaceuticals. The detailed characterization of the drying of the resulting drops is an important component of designing any spray drying process. This study focuses o

Polyethylene, the most ubiquitous polymer in use, is a semi-crystalline material. Solvents enter only the amorphous phase. The solubility in that phase, however, cannot be characterized by the amorphous solubility found above the melt temperature. Th

Diffusion of penetrants in polyethylene below the melt temperature is heavily dependent on the crystallinity of the polyethylene, the temperature of the experiment, and the concentration of solvent in the polymer. As the crystallinity of the polyethy

Thermodynamic properties of a hypromellose acetate succinate (HPMCAS-L)-acetone-water system at temperatures below the glass transition temperature of HPMCAS-L were investigated. The solubility of water and acetone in HPMCAS-L is important for the op

Poly(styrene-co-acrylonitrile) (SAN) foam is produced for applications requiring high impact and/or high solvent resistance. The use of environmental friendly carbon dioxide is preferred as a foaming agent when possible. Little or no data are availab

There are indications in the literature that the devolatilization of some polymers, particularly polyethylene, can be enhanced by the addition of water, generally in the form of steam. In this study three different experimental methods were used with

A model has been developed to describe the simultaneous diffusion and solvent-induced crystal formation in polymers based on the idea that crystal formation is governed by polymer chain mobility and a thermodynamic driving force. The polymer chain mo

The solubility and diffusivity of cyclohexane in a very low density polyethylene (VLDPE) have been measured over a range of temperatures and concentrations. These data provide an interesting contrast to similar data for high density polyethylene. Abo

Polyvinyl chloride (PVC) is a widely used polymer for many types of products, some of which come into close contact with people. To obtain flexibility a variety of plasticizers are added to PVC. Over the years these additives have been investigated e

This paper provides a review of the measurement, data reduction, and correlation of diffusivities using the free-volume theory for polymer–solvent systems, particularly in the range of very low solvent concentration. The experimental methods discus
