The crosslinking reaction of three series of a,w-dihydroxy oligo(alkylene maleate)s with a trifunctional isocyanate was followed by dynamic mechanical analysis and FTIR spectroscopy. The evaluation of rheological parameters, such as storage G' and loss modulus G", was recorded. A typical G' versus time curve has a characteristic "S" shape, indicating autoacceleration of the crosslinking reaction. The whole curing process starting from G'equal G" or the beginning of gelation is described by adoi:10.2298/jsc0303147d fatcat:musbkmcrhffwzljljpmusvuaqq
