Propargylic-Terminated Prepolymers. 5. Mechanistic and Kinetic Studies of the Polymerization Reaction of Compounds with an Imide Group meta to the Propargylic Function

Abstract

We have synthesized two functionalized prepolymers with an imide group meta to the propargylic function in their central skeleton. Based on data obtained by a variety of solid and liquid state physicochemical techniques, we show that meta substitution modifies the reaction path and leads to the formation of two chromenes, α and β. In addition, the reaction kinetics and thermal stability of the final system are affected by the presence of an imide group in the structure of the propargylic prepolymer.
