  • Patent number: 4081427
    Abstract: This invention relates to a process of reformulating a solvent polyester-type resin, such as employed in electrical insulation, for example in wire enamels, to a solventless polyester-type wire resin of similar properties which is characterized by increasing the relative hydroxy-functionality of said polyester-type resin as compared to the hydroxy-functionality of a corresponding solvent-type wire resin.In the preferred embodiment the increased hydroxy-functionality, in whole or in part, is derived from the use of, or the increased content, of tris(2-hydroxyethyl) isocyanurate. The polyester-type wire enamels include polyesters and polyesters containing other groups such as polyester-amides, polyester-imides, polyester-amide-imides, etc. By doing this, resins having the desired properties as well as viscosities suitable for wire insulation can be made and applied in solventless systems.

  • Patent number: 4064088
    Abstract: The invention relates to the manufacture of urea-formaldehyde condensation polymers containing sulpho groups. The starting material is a urea-formaldehyde precondensate, and a condensation polymer of naphthalenesulphonic acid and formaldehyde is used as the acid catalyst for the subsequent polycondensation of the urea-formaldehyde precondensate. The peculiarity of this polycondensation is that the condensation catalyst is incorporated into the polymer structure of the UF polymer.The products obtained according to the invention are distinguished by improved surface affinity coupled with interparticle porosity. They can be used as fillers, as adsorbents, as carriers and as thickeners.
