The addition of catalyst to polymerize the propargylic function causes a decrease in the reaction onset temperature T0. Depending on the nature of the catalyst we demonstrate different reaction mechanisms involving the formation of the chromene group (as in the case of non-catalysed systems), of the Sabourin dimer, or the cyclooctatetraene structure in the molten state. We thus show that the catalytic effect is more determinant towards the propargylic function than towards the chromene group.

AbstractAutism spectrum disorder (ASD) subjects can present temporary behaviors of acute agitation and aggressiveness, named problem behaviors. They have been shown to be consistent with the self-organized criticality (SOC), a model wherein occasionally occurring “catastrophic events” are necessary in order to maintain a self-organized “critical equilibrium.” The SOC can represent the psychopathology network structures and additionally suggests that they can be considered as self-organized systems.
