“…Frontal polymerization (FP) is a synthetic technique that allows the conversion of monomer into polymer by formation and consequent propagation of a hot polymerization front, able to self‐sustain and propagate throughout the monomeric mixture. This technique allows obtaining polymer materials by a simple reaction route, short time, and low energy consumption …”

The frontal ring opening metathesis polymerization (FROMP) of dicyclopentadiene (DCPD) in the presence of limonene, using second generation Grubbs’ catalysts, is reported. The effect of limonene on the amount of catalyst and the typical frontal polymerization parameters, as maximum temperature (Tmax) and velocity of the front (Vf), is studied. In addition, the influence of limonene on the mechanical properties of the polymeric samples is reported. Finally, a deep study on the swelling properties of polymers is done. It has been demonstrated that limonene acts as both inhibitor and solvent of the catalyst. The Tmax, Vf, Tg, and Young modulus values decrease as the amount of limonene increases, and the polymer samples swell in THF depending on the amount of limonene. All results indicate that the limonene addition on FROMP of results in advantages on the polymerization reaction and its parameters and on the final polymer properties. © 2015 Wiley Periodicals, Inc.

“…In particular, the possibility was shown to regulate not only the polymer conversion but also the molecular mass characteristics of formed poly‐MMA. On the other hand, the numerical calculi of a two‐dimensional model of frontal polymerization of ϵ‐caprolactam show no jets during concomitant polymerization and crystallization according to the investigations in ref …”

“…On the other hand, the numerical calculi of a two-dimensional model of frontal polymerization of e-caprolactam show no jets during concomitant polymerization and crystallization according to the investigations in ref. [9,10] A typical example for obtaining solid polymers is the process of interaction between epoxy with aromatic amines. As a model for the specified systems the kinetics and mechanism of phenyl-glycidil ether with aniline interaction was studied.…”

A one‐dimensional and two‐dimensional model of the frontal reaction of epoxy compounds by aromatic amines in tubular flux reactors is investigated. The influence of relevant kinetic factors (velocity, activation energy, and others) on the velocity of the traveling front, the heat regimes of the reactor, and the geometric dimensions of the reactor is studied. An optimal steady‐state condition of the tubular reactor under continuous action is determined. Profiled armored carbon and glass plastics forming laboratory installation are constructed, as derived from the obtained theoretical results. It is shown that the theoretical and practical results are in satisfactory agreement. Several physico‐mechanical properties (e.g., bending strength, longitudinal modulus of elasticity), as based on the reactor wall temperature, angle of armoring, and tension are determined.

“…Considering this fact and following the data from [1,2], let us consider the physical prerequisites for the existence of stationary waves of frontal polymeriza tion. Despite a large number of studies in this field [3][4][5][6], no data are available on the existence and unique ness of steady state regimes of radical frontal poly merization of vinyl monomers.…”

Physical causes of the absence of steady state heat regimes of frontal radical polymerization of vinyl monomers at a nonzero rate of chemical transformations of initial reaction media are discussed. The effect of the dimensionless "cutting" temperature of a heat generation source on the relative velocity of poly merization front propagation is studied. There is an interval of "cutting" temperatures of the source where the velocity of polymerization front propagation is independent of the "cutting" temperature of the source. As for combustion processes, the front velocity depends on dimensionless parameters that are intrinsic for the heat regime of the process.
