Four component Passerini polymerization of bulky monomers under high shear flow

We introduce a four component Passerini polymerization utilizing sterically bulky isocyanide monomers. Under typical Passerini conditions, bulky isocyanides do not react within standard Passerini reaction timescales (hours). We overcome this challenge via the unique physiochemical conditions present in a vortex fluidic device, reducing the reaction time to 2 h on average. Under these high-shear thin-film conditions, bulky isocyanides are readily incorporated into the multicomponent polymerization without the need of high-pressure or temperature. Finally, we demonstrate that the four component approach using functional cyclic anhydrides allows for post-polymerization modification.
Thermal behaviour of the copolymers of acrylonitrile with methyl acrylate and itaconic acid or its derivatives
Shlyakhtin, Andrei V. Lemenovskii, Dmitrii A. Nifant'Ev, Ilya E.
Itaconic acid monoesters and monoamides, such as 2-carbamoylmethacrylic acid, N-octyl-2-carbamoylmethacrylic acid and 2-methoxy- carbonylmethacrylic acid, smoothed the peak of heat release upon the thermal cyclization of acrylonitrile copolymers with commensurable effectiveness, and they can serve as competitive substitutes for itaconic acid in the synthesis of carbon fiber precursors.
