  • METHOD FOR PRODUCING POLYURETHANE POLYMERS WITH REDUCED HEAT VALUE
    Publication number: 20200362090
    Abstract: The invention relates to a method for producing a polyurethane polymer, comprising the step of reacting a polyol component with a polyisocyanate component, the polyol component comprising an oxymethylene polyol. The ratio of the polyol component to the polyisocyanate component is selected such that the polyurethane polymer obtained by the reaction has a content of oxymethylene groups from the oxymethylene polyol of ?11 wt. % to ?50 wt. %, preferably ?11 wt. % to ?45 wt. %, and the content of oxymethylene groups from the oxymethylene polyol is defined by means of proton resonance spectroscopy.

  • Phosphorescent metal complex, process for production and light-emitting component
    Patent number: 9169434
    Abstract: This invention presents, firstly, the principle that simple and known emitter materials which are uncharged per se, as known, for example, from OLED technology, can be converted to a charged species by the introduction of a charged imidazolinium radical. This charged species can then be used in organic light-emitting electrochemical cells.
