  • Patent number: 9040617
    Abstract: Water-borne cross-linking polymeric compositions and related embodiments, such as methods of making and using the compositions, as well as products formed with said compositions are described. The water-borne composition may comprise one or more polymers formulated from one or more monomers of which at least one is a monomer that yields acetaldehyde as a hydrolysis product, and incorporating cross-linking functionality such as, but not limited to, carbonyl or epoxy functionality, and a blocked cross-linking agent, for example, a hydrazone. Neither the cross-linking functionality nor the acetaldehyde reacts with the blocked cross-linking agent; however, the blocked cross-linking agent is capable of conversion to an alternative form cross-linking agent such as, but not limited to, a hydrazide, to yield a cross-linked polymer. The alternative form cross-linking agent may be formed in an equilibrium reaction including the blocked cross-linking agent.

    Abstract: What are described are polyvinyl ester dispersions which are prepared in a multistage process and have a low content of polymerized acids or acid anhydrides. They can be obtained by a multistage process in which a polyvinyl ester dispersion is obtained in a first stage, monomers in dissolved or pure form are added to the reaction mixture in a second stage and then the polymerization is started again. The polymer dispersions obtained in this way are notable for a low coagulum content and for increased tensile strengths of the films formed therefrom.

  • Publication number: 20140018473
    Abstract: Disclosed are aqueous latex-based coating compositions which comprise a blend of an ethylene-vinyl acetate emulsion copolymer component and a selected type of acrylic emulsion copolymer component. The acrylic copolymer component comprises primarily acrylate ester co-monomers or acrylic ester co-monomers and vinyl aromatic, e.g., styrene, co-monomers. The blend of these two emulsion copolymer types also contains a specific type of hydrazine-based, water-soluble cross-linking agent which can eventually react with the acrylic emulsion copolymer component. The acrylic emulsion copolymer is one which contains minor amounts of both 1) carboxy functional co-monomers such as itaconic and/or (meth)acrylic acids, and 2) keto- or aldehyde-containing co-monomers such as diacetone acrylamide. Such latex-based coating compositions can be formulated in the form of water-based paint compositions.

  • Publication number: 20130123383
    Abstract: This invention focuses on improving mechanical properties without deteriorating flame retardancy in peroxide cross-linked and radiation cross-linked thermosetting clean flame retardant compositions. Optimal mechanical properties can be obtained by modifying the ratios of MAGNIFIN H10A/Ultracarb LH 15X in peroxide crosslinked or radiation crosslinked clean flame retardant composition. Higher tensile strength can be obtained by higher MAGNIFIN H10A content, and higher elongation at break can be obtained by higher Ultracarb LH 15X content. The invented compositions show excellent mechanical properties, flame retardancy, thermal properties, electrical properties and process ability for meeting the stringent specifications of wire and cable industry. Composition is made of 100 parts by weight of resin (polyolefin or 100 parts by weight of polyolefin/EPDM), 90-150 parts by weight of MAGNIFIN H10A/Ultracarb LH 15X as main flame retardants, 1-20 parts by weight of auxiliary secondary flame retardant agents and 0.2-1.
