We report the visualization and quantitative analysis of the cross-link structure in model core/shell hydrogel polymers on the microscopic scale, in a fully swollen state, using soft X-ray microscopy. The cross-link density in these materials and the

Anionic and nitroxide-mediated (NM) radical polymerization works well for styrene but not for acrylates. We have overcome this problem and successfully prepared styrene-b-n-butyl acrylate (S-BA), styrene-b-methyl methacrylate (S-MMA), styrene-b-isopr

The morphology, size distributions, spatial distributions, and quantitative chemical compositions of co-polymer polyol-reinforcing particles in a polyurethane have been investigatedwith scanning transmission X-ray microscopy (STXM). A detailed discus

Superabsorbent polymers are often designed with increased density of crosslinking in the outer layer of the particles in order to improve liquid retention under load. For efficient product design, it is desirable to directly measure the spatial varia

The production of rubber modified thermoplastics can exceed rates of 30,000 pounds per hour. If a production plant needs to equilibrate or has an upset, that means operating costs and lost revenue. Results of transmission electron microscopy (TEM) ca

The interpretation of, and information available from a transmission electron photomicrograph, frequently depend upon specimen preparation. A major consideration in the selection of a preparation method is the potential for preparation artifacts. The
