  • Patent number: 11905392
    Abstract: Binder compositions are described that include a phenol, a urea compound, formaldehyde, and at least one cyclic urea-dialdehyde compound. The cyclic urea-dialdehyde compound forms crosslinking bonds between polymers of phenol-urea-formaldehyde when the binder composition is cured. Also described are methods of making fiberglass insulation products using the above-described binder compositions. The methods may include contacting the binder composition with glass fibers and forming an amalgam of the binder composition and the glass fibers. The amalgam may be heated to form mats of the glass fibers and binder. The mats may be processed into the fiberglass insulation products.

  • Patent number: 6001949
    Abstract: One of the objects of the present invention is to offer novolak type phenolic resins which use phenols and aldehydes as raw materials and give narrow molecular weight distributions.The novolak type phenolic resins of the present invention are those obtained by condensation reaction of phenols with aldehydes in the presence of an oxycarboxylic acid having carboxyl groups, --COOH, and alcoholic hydroxyl groups, --OH, in one molecule. Thus obtained novolak type phenolic resins show narrow molecular weight distributions, lower viscosity in molten state and, as a consequence, uniformity in curing time.

  • Patent number: 5952425
    Abstract: Phenolic resin curatives having a majority of dibenzyl ether linkages were unexpectedly found to be very effective in curing unsaturated rubbers in a blend of a crystalline polyolefin and said rubber. Their effectiveness exceeds that of conventional phenolic resins for many thermoplastic vulcanizate compositions allowing for the reformulation of the recipes with lower amounts of curatives and equivalent or superior physical properties in the resulting thermoplastic vulcanizate.

  • Patent number: 5932389
    Abstract: This invention relates to alternating and block copolymer resins of uniform and controlled chain length and methods for preparing the same. The alternating copolymer resins are formed from the reaction of a bisoxymethylphenol, a reactive phenolic compound and a monooxymethylphenol. The alternating copolymer may then be further reacted with a second reactive compound in the presence of an aldehyde to form the substantially blocked copolymer. The resins of the invention are characterized by a low molecular weight distribution. The resins are useful for the formulation of high resolution photoresist materials.
