We show, numerically, that the "gel point" described as the onset of the gelation phenomena and measured experimentally, corresponds to an accumulation point of the extreme values of the derivatives of the gelation curve. We define the "critical point of a sigmoidal curve" as the limit of the points where the derivatives reach their extreme values, provided that this limit exists.eninfo:eu-repo/semantics/openAccessMolecular-Size DistributionPolymersGelationConference Object574WOS:00035259560000510.1088/1742-6596/574/1/0120052-s2.0-84921696296N/AN/A
