  • Patent number: 8133952
    Abstract: A formaldehyde-free curable aqueous composition containing polyvinyl alcohol, a multi-functional crosslinking agent, and, optionally, a catalyst. The composition may be used as a binder for non-woven products such as fiberglass insulation. The non-woven products are formed by contacting the formaldehyde-free curable aqueous composition with fibrous components and the mixture is cured to form a rigid thermoset polymer providing excellent strength and water resistance of the cured nonwoven product.

  • Patent number: 8034885
    Abstract: The present invention provides a novel one-step process for preparing an aqueous polymer dispersion by the free radical aqueous emulsion polymerization comprising mixing at least water, a dispersant, and an oil-soluble initiator; raising a temperature from the starting to the end reaction temperature while metering at least ethylenically unsaturated monomers and a water-soluble initiator into a reaction vessel, conducting polymerization of the monomers in the presence of the water-soluble initiator at a temperature up to the end reaction temperature, and when the temperature has reached the end reaction temperature, conducting polymerization by the oil-soluble initiator. The oil-soluble initiator is inactive at the starting reaction temperature and becomes more active as a temperature approaches the end reaction temperature at which the oil-soluble initiator is fully active.

  • Patent number: 8022155
    Abstract: The invention relates to polymerizable compositions which comprise 10-80% by weight of a reactive diluent based on acrylic acid or methacrylic acid derivatives, and 10-50% by weight of a monomer of the indicated chemical formula which is liquid or which can be dissolved in the formulation. The formula may contain amino acid residues or peptide sequences, especially such that are specific of the collagen. These structural elements allow the enzymatic degradation of the polymers of the inventive composition.
