Kinetics modelling of the crosslinking in the photopolymerization of furfuryl methacrylate in bulk

Study of Effect of Bifunctional Crosslinking Agent in Polyvinylalcohol-Based Photopolymerizable Holographic Recording Material Using Angular Responses

“…The theoretical treatment in these reactions is too complex due to the high number of steps, and as a consequence it is difficult to obtain analytic expressions for describing the kinetics of polymerization, thus numerical methods are used to solve this problem. [11][12][13][14][15][16][17] Generally, radical polymerization is divided into three stages: initiation, propagation and termination. 15) A possible mechanism of initiation for the composition of this material is proposed in eqs.…”

Kinetic Study of the Thermopolymerization of Furfuryl Methacrylate in Bulk by Mathematical Modeling. Part A: Simulation of Experimental Data and Sensitivity Analysis of Kinetic Parameters

“…[1][2][3][4][5][6][7][8][9] In particular, these compounds have been considered as possible candidates in the formulation of various products for use in dentistry, such as pit and fissure sealants, and in orthopedics as bone cements. As a result of the promising application of these compounds, theoretical interest in the mechanism of their polymerization is growing.…”

“…In our recent work, a mathematical model developed by the method of moments ('cross-linked model') was applied successfully to the photochemically initiated polymerization [using azoisobutyronitrile (AIBN) as photo-initiator] of these compounds which gave good results for the fitness of experimental data and allowed the rate constants of all simple steps to be estimated as well as the concentrations of radicals, the molecular weight averages (which characterize the size of the primary chains in the network) and the composition of pendant groups. [1,3,7,9] The aim of this work was to extend the application of the proposed model to the thermopolymerization of two acrylfuranic monomers, namely, FM and carbomethoxyfurfuryl methacrylate (CMFMA, see Figure 1) in order to estimate the versatility and utility of the developed tool for the theoretical in-depth study of the kinetics of formation of three-dimensional networks for different furanic structures under different experimental conditions. With this idea in mind, for the current work the cross-linked model was applied to the polymerization, yielding up to 90% conversion of the monomer over a temperature range of 333-353 K. [13] It is logical to expect that such drastic variations both in the experimental conditions (compared to the preceding photocured system) and in the monomer structure (notably the presence of the carbomethoxy group in the C-5 position of the furan ring) would require appropriate modification to the previously developed model to be made.…”

“…This formulation will be applied specifically to the crosstermination step (k tc ) between acrylic (A) and allylic (F) macroradicals (see Figure 1) which is the only step, according to sensitivity analysis leading to polymer formation. [1,4] …”

Dynamical Model to Describe the Interactions between the Chemical Components in Environment of Photopolymerization of MMA by Dye/Amine Systems

“…Theoretical studies about process of photopolymerization are described by statistical methods [17][18][19], analysis by interpolation, or similar methods [20,21]. However, these works do not present evidences of predictability.…”
