  • Publication number: 20140224424
    Abstract: The use of a mixture of 5-pyrimidinol derivatives with sterically hindered phenol derivatives for adjusting the reactivity and the gel time of resin mixtures and reactive resin mortars based on radically polymerizable compounds is described. Furthermore, a resin mixture containing the inhibitor combination, a reactive resin mortar containing this resin mixture and two-component mortar systems with the reactive resin mortar according to the invention and a hardener with improved stability in storage and good low-temperature hardening properties are also described. The resin mixture according to the invention is suitable in particular for chemical fastening of construction elements in boreholes in various substrates.

  • Publication number: 20050065174
    Abstract: Compounds, preferably 5-pyrimidinol and 3-pyridinol derivatives, that act as effective chain breaking antioxidants of both the lipid and water-soluble variety (analogous to the natural Vitamins E and C), many of which are more reactive toward peroxyl radicals than the most potent form of Vitamin E. These compounds may exhibit many chemopreventive effects associated with conditions in which free radical-mediated cellular damage or disruption is implicated and Vitamins E and C are shown to have protective effects. Additionally, these compounds should be excellent oxidation inhibitors as additives to fuels, lubricants, rubber, polymers, chemicals, solvents and foodstuffs.
