  • Patent number: 8802848
    Abstract: The present invention relates to Melamine based Mannich compounds of the general formulae (1)-(12) and a process for synthesizing melamine based Mannich-products comprising the steps of a) reacting at least one substituted melamine with at least one aldehyde, in particular formaldehyde, under basic conditions to form at least one OH-containing compound, b) reacting the at least one OH-containing compound in the presence of a catalyst to form at least one mannich-base, c1) reacting the at least one mannich-base with at least one enol-forming carbonyl compound, or c2) reacting the at least one mannich-base with at least one aromatic compound, and d) working up the reaction mixture. The invention relates further to precondensates obtainable from these products.

  • Patent number: 8114953
    Abstract: The invention relates to melamine-formaldehyde condensates with thermoplastic properties that can be produced from formaldehyde and melamine derivatives, wherein at least one of the melamine derivatives organic radicals R have been used to substitute at least four of the total of six hydrogen atoms of the three melamine amino groups, and wherein the organic radicals R are mutually identical or different. The invention also relates to a process for production of the melamine-formaldehyde condensates, use thereof, and an analytical method for determining the constitution of the melamine-formaldehyde condensates.

  • Patent number: 6391953
    Abstract: The invention relates to a coating compound for fibers and to a process for the production thereof The invention relates in particular to a preparation agent for elastanes, based on a dispersion of fatty-acid metal salts and an agglomeration inhibitor in polyorganosiloxanes and mineral oils. The preparations are produced by a precipitation process from which fined-particle and sedimentation-stable dispersions with a narrow particle size distribution are obtained which are free from agglomerates.
