Some rules governing the extension of the front of radical polymerization of vinyl monomers

Frontal Reaction of Epoxy Oligomers in Tubular Flux Reactors

“…For simplicity, a symmetric heat removal on the lateral surfaces of the reactor (r ¼ r 0 ; r ¼ r 1 ) is assumed. Three basic parameters, the flux velocity (u), its temperature (T 0 ), and the coefficient (a) for heat-exchange with environs were varied for the numerical solution of Equation (5)(6)(7)(8)(9)(10).…”

“…[4] In the work by Aleksanyan et al, on some rules governing the extension of the polymerization front, numerical calculations were performed of the heat conductivity equation with the kinetic equations of radical polymerization. [5] The analysis of the obtained results allowed to establish the general laws of frontal regimes as well as the necessity for taking into account in theoretical investigations a gel-effect existing in the polymerization process. Actually, considering the influence of the gel -effect on the kinetics of radical polymerization under the conditions of the polymerization front propagation allowed to describe quantitatively the experimental results for the velocity of MMA frontal radical polymerization.…”

Photoinitiating systems and kinetics of frontal photopolymerization processes – the prospects for efficient preparation of composites and thick 3D structures

“…27 There are publications in the literature focusing on approximating the kinetic basis of the phenomena occurring during the FPP techniques described above. 19,[28][29][30][31][32][33][34] Initiators of radical frontal photopolymerisation When choosing an initiator for FPP, it is necessary to pay attention to several important aspects. First, the appropriate type of initiator for the initiating system is needed.…”

Bismuthonium‐ and pyrylium‐based radical induced cationic frontal polymerization of epoxides

“…Whenever a polymerization reaction occurs directionally with a local reactive zone, the term frontal polymerization (FP) is used. The first appearences of FP were in the 1970s 1–3 . The local reactive zone or front propagates through the curable material.…”
