    Abstract: A new class of polymeric corrosion inhibiting compositions incorporating pendant heterocyclic groups which are surprisingly effective copper corrosion inhibitors are disclosed. The polymers form a protective barrier on metallic components to aqueous systems and remain substantive on metallic surfaces over a wide pH range. Moreover, the polymers are resistant to oxidizing biocides, and are substantially impervious to repeated or prolonged exposure to corrosive agents.

    Abstract: The use of a new class of polymeric corrosion inhibiting compositions incorporating an ethylenically unsaturated monomer and an imide or amide with pendant heterocyclic groups is disclosed. The polymers form a protective barrier on metallic components to aqueous systems and remain substantive on metallic surfaces over a wide pH range. Moreover, the polymers are resistant to oxidizing biocides, and are substantially impervious to repeated or prolonged exposure to corrosive agents.

    Abstract: A method for the protection of wood and other wood materials without affecting dimensional stability or surface integrity of the treated material is described. The method involves treating wood material with an iron salt and selected oxidants where the iron salt is preferably complexed with organic chelating ligands. Preferably, a microbicidal agent is also incorporated into the method to provide treated wood products that demonstrate excellent surface integrity, dimensional stability and retention of the infused microbicidal agents for extended periods of time without incurring the detrimental environmental effects of conventional chromium or copper-based inorganic salt preservation methods.

    Abstract: Disclosed is a method of inhibiting the growth of microorganisms in, at, or on a locus subject to microbial attack, comprising introducing to said locus an antimicrobially effective amount of at least one alkoxy disulfide of formula: R 1 -CHR 3 -O-S-S-O-CHR 4 -R 2 wherein:

    R 1 , R 2 are independently selected from 5- or 6-membered aromatic rings, optionally substituted with up to 3 e · donating substituents of which 2 can optionally be combined to form another ring; and
    R 3 , R 4 are independently selected from H, CH 3 , or CH 2 CH 3 .
