Polythioether polymers, sealants containing polythioether polymers, and compounds useful as stabilizing monomers in the manufacture of polythioether polymers are provided. In many embodiments the polymers and sealants demonstrate reduced risk of spoilage that may be caused by low temperature storage of the polymer or uncured sealant. Compounds useful as stabilizing monomers include compounds according to formula I:

CH.sub.2CR.sup.1CHR.sup.2SR.sup.3SCHR.sup.4CR.sup.5CH.sub.2[I]

wherein R.sup.1, R.sup.2, R.sup.4 and R.sup.5 are independently selected from H, CH.sub.3 or C.sub.2H.sub.5, and wherein R.sup.3 is selected from divalent groups comprising 2-12 carbon atoms, 0-5 ether oxygen atoms and 0-5 thioether sulfur atoms, which may be straight, branched or cyclic.

A variety of anodically-coloring electrochromic molecules are provided. In particular, anodically-coloring electrochromic molecules and devices are provided that allow for tuning the absorption bands in the cation state across the visible spectrum while demonstrating little to no coloring or visible absorption in the neutral state, resulting in high-contrast devices. Electrochromic devices are also provided, as well as methods of making the devices and molecules, and methods of use thereof.

The present invention relates to improved hydrogel materials using water gellants that are comprised of polymer backbones P to which hydrogen bonding 4H-units are covalently attached via a hydrophobic linker L. Optionally, the hydrogel contains additional ingredients or additives. These new reversible hydrogels can easily be fine-tuned in their mechanical performance and function and are especially suitable for biomedical applications.

Described here are polyphenylene sulfide (PPS) polymers having significantly improved processability. It was surprisingly found that PPS polymers, terminated with specific end-capping agents in specific amounts, had significantly improved melt stability. Because of the significantly improved melt stability, the PPS polymers can be advantageously incorporated into melt processing techniques.
