More specifically, described are H2S generating polymers comprising at least one thioamide group. The H2S generating polymers can provide controlled site-specific release of H2S once implanted at or within the target surgical site by hydrolysis of the thioamide group in physiological media. The H2S generating polymers can be coated onto a medical device, formed into a medical device or combined with one or more other polymers to form a polymer system. Also described are methods of treating restenosis and inflammation and promoting vasodilation utilizing such medical devices.

  • Patent number: 8106142
    Abstract: Polyacetylinic oligomers suitable for high-temperature polymer-matrix composites are provided. The polyacetylinic oligomers have the formula: D-A-D wherein D is an endcap including at least one crosslinking functionality; and A is backbone selected from the group consisting of imidesulfone; ether; ethersulfone; amide; imide; ester; estersulfone; etherimide; amideimide; oxazole; oxazole sulfone; thiazole; thiazole sulfone; imidazole; and imidazole sulfone. At least one ethynyl functional group, however, is incorporated into the backbone such that crosslinking is not only realized at the endcaps but also at the ethynyl groups within the backbone of the oligomer itself.

  • Publication number: 20110319587
    Abstract: A method for producing a polyarylene sulfide resin includes allowing a polyhaloaromatic compound (a), an alkali metal hydrosulfide (b), and an organic acid alkali metal salt (c) to react with each other in the presence of a solid alkali metal sulfide and an aprotic polar organic solvent, wherein the reaction is conducted using the organic acid alkali metal salt (c) in a ratio of 0.01 moles or more and less than 0.9 moles relative to a total of 1 mole of the solid alkali metal sulfide and the alkali metal hydrosulfide (b) in a state where the amount of water existing in the reaction system is 0.02 moles or less relative to 1 mole of the aprotic polar organic solvent. Thus, it is possible to provide a method for producing a polyarylene sulfide resin with which high productivity is achieved on an industrial scale, and the molecular weight of the resulting polyarylene sulfide resin can be significantly increased.
