    摘要: A molded polymer article comprises a main molded body having on the surface thereof a hydrophilic polymer layer, the article being obtained by polymerizing both a monomer having a hydrophilic group and coated on the surface of a hydrophilic mold, and a polymerizable composition consisting essentially of a monomer and/or oligomer and placed in the mold. The hydrophilic polymer layer has excellent adhesiveness to the main body of the molded polymer article and excellent durability, so that the high hydrophilic property can be maintained, even when the article is exposed to external forces such as friction, over a long period of time. The molded articles are therefore useful as, in particular, contact lenses.

    摘要: Novel water-soluble mono and disaccharides of 1,2-dithiins, as well as methods for their synthesis and the synthesis of 3,6-bis(hydroxymethyl)-1,2-dithiin, are provided. The water-soluble compounds have useful medicinal applications, e.g., as an antifungal agent or antibacterial agent in a pharmaceutically acceptable carrier.
