The gel conversions (โฃ gel ) for the polycyclotrimerization of aromatic dicyanates are significantly higher than the classical mean-field value of 0.5. The reasons for the higher gel conversion, which is consistent with all experimental results of different structures of monomers, were inductively a
Comparisons of the effectiveness of different theoretical equations to ยฎt various sets of experimental T g versus conversion data are made. Among all the theoretical expressions for the T g versus conversion relationship, one-parameter equations give excellent ยฎtting to the experimental data. The va
Polycyclotrimerization of a flexible aromatic dicyanate with a Schiff base structure was studied by means of differential scanning calorimetry (DSC). The study on dynamic DSC evaluated an apparent activation energy (En) of 75.8 kJ/mol and autocatalytic first-order kinetics with rate expression A f (
