The present invention relates generally to high sulfur content polymeric materials and composites, methods for making them, and devices using them such as electrochemical cells and optical elements. In one aspect, a polymeric composition comprising a copolymer of sulfur, at a level in the range of at least about 50 wt % of the copolymer, and one or more monomers each selected from the group consisting of ethylenically unsaturated monomers, epoxide monomers, and thiirane monomers, at a level in the range of about 0.1 wt % to about 50 wt % of the copolymer.

Improved aromachemical derivatives, and fragrances and flavorings including the derivatives, that have a longer useful shelf life than the aromachemicals from which they can be derived, are disclosed. In particular, the derivatives maintain the fragrance characteristics of the aromachemicals, while lowering the allergic properties, increasing the stability, and / or increasing the odor intensity. Also disclosed are methods of making the derivatives, and articles of manufacture including the derivatives. In one embodiment, the derivatives are prepared by replacing one or more double bonds in citral with a thioether, cyclopropyl, oxirane, or thiirane group. The cyclopropane ring can be unsubstituted, or substituted with one or two lower alkyl, preferably methyl groups. The alkyl groups can optionally be substituted, for example, with electron donating groups, electron with drawing groups, groups which increase the hydrophilicity or hydrophobocity, and the like. In another embodiment, the derivatives are prepared by replacing the aldehyde group in the essential oil with a nitrile, methyl ether or acetal group. The acetal groups can provide the compounds with a long lasting flavor or fragrance, where the acetals slowly hydrolyze to provide the aldehyde group in the parent essential oil. In some embodiments, both the aldehyde and at least one of the double bond functional groups are both derivatized as described herein. Examples of suitable articles of manufacture include candles, air fresheners, perfumes, disinfectant compositions, hypochlorite (bleach) compositions, beverages such as beer and soda, denture cleanser tablets and flavored orally-delivered products such as lozenges, candies, and the like.

The invention discloses application of the compound (I) as shown in formula (I) in preparing a pharmaceutical composition for treating cerebrovascular spasm. Animal experiments confirm that: SB-3CT has certain curative effect to CVS after SAH (subarachnoid hemorrhage), and can mitigate the thickening degree of spastic vessel walls and the lumen stenosis, thus providing a new treatment approach for CVS after SAH.
