    Description / Table of Contents: A Monte Carlo model for the simulation of the process of network building by polycyclotrimerization of difunctional monomers basing on the reaction mechanism of the polycyclotrimerization of aromatic dicyanates was developed. The experimental dependences of the average molar mass, the mass fractions of the first oligomers and of the gel fraction on the conversion of functional groups, measured for the reaction of 2, 2-bis(4-cyanatophenyl) propane in bulk, can be well fitted by the model. Furthermore, the possiblities of the simulation of intramolecular cyclizations and substitution effects are discussed.
    Notes: Auf Basis des Reaktionsmechanismus der Polycyclotrimerisierung aromatischer Dicyanate wurde ein Monte-Carlo-Modell zur Simulation der Netwerkbildung durch Polycyclotrimerisierung difunktioneller Monomere entwickelt. Die experimentell ermittelten Abhängigkeiten der mittleren Molmasse, der Massenanteile der ersten Oligomere und des Gelanteils vom Umsatz der funktionellen Gruppen bei der Reaktion von 2, 2-Bis (4-cyanatophenyl) propan in Schmelze werden durch das Modell gut erfaßt. Weiterhin werden Möglichkeiten der Simulation von intramolekularen Cyclisiierungen und Substituenteneffekten diskutiert.
