Definitions

  • the OH number (also: hydroxyl number) indicates in the case of a single added polyol its OH number.
  • Information on the OH number for mixtures relates to the number-average OH number of the mixture, calculated from the OH numbers of the individual components in their respective molar proportions.
  • the OH number indicates the amount of potassium hydroxide in milligrams, which is equivalent to the amount of acetic acid bound upon acetylation of one gram of the substance. It is determined in the context of the present invention according to the standard DIN 53240-1 (June 2013). "Functionality" in the context of the present invention denotes the theoretical mean value calculated from the known starting materials and their quantitative ratios (number of functions which are reactive toward isocyanates or polyols relative to polyols in the molecule).
  • the invention relates to a process according to any of embodiments 1-9, characterized in that the phosphazene is a cyclic phosphazene and preferably has a structure of the general formulas (III) to (VI)
