“…The FT‐IR spectrum of a typical P GMA‐TAIC‐EGDMA (a) and P GMA‐EGDMA (b) beads are presented in Figure 2 which ensured the presence of oxirane functionality and triazine ring of TAIC. The IR spectrum gave a prominent band at 1260 cm −1 due to the symmetrical stretching of the oxiranoyl ring 8, 30. Another band at 908 cm −1 due to epoxy ring out of plane vibration further confirmed the presence of epoxy group and hence GMA 31.…”

A novel macroporous poly(glycidyl methacrylate-triallyl isocyanurate-ethyleneglycol dimethacrylate) copolymer, hereinafter P GMA-TAIC-EGDMA , of controlled bead size was prepared via free radical suspension copolymerization. The effects of varying the concentration of crosslinking agents and porogenic diluent on the average pore diameter, pore size distributions, specific surface area, and pore volume of the copolymer matrix were thoroughly investigated. The spherical beads were characterized by elemental analysis, Fourier transform infrared spectroscopy, and thermogravimetric analysis. The specific pore volume, average pore diameter, pore size distribution, and the specific surface area were measured by Mercury intrusion porosimetry and BET adsorption method, respectively. The porous properties of the polymer matrix are a direct consequence of the amount and quality of the porogenic solvent, the percentage of crosslinking monomers, and the ratio between the monomers and porogen phases. When the polymer was prepared at 30 and 40% crosslinking density, and 75 and 100% diluents, respectively, it showed a fine beads morphology, mechanical stability and pore size distributions. By comparing the copolymers P GMA-TAIC-EGDMA and P GMA-EGDMA , it was found that the former is more stable both thermally and mechanically than its predecessor. The presence of epoxide functionalities of macroporous P GMA-TAIC-EGDMA beads makes it a versatile carrier. The resulting polymers have the potential for wide applications.

“…The main difference in the spectra is that the peak at 1250 cm −1 is highest for the epoxy excess case as in the pure TGDDM spectra. Field et al18 studied several epoxy compounds, and concluded that this band corresponds to the epoxy group, implying that the homopolymerization reaction was not complete.…”

ABSTRACT:The uncatalyzed cure of a commercial tetrafunctional epoxy monomer TGDDM (N,N,NЈ,NЈ-tetraglycidyl-4,4Ј-diaminodiphenylmethane) with hexahydrophthalic anhydride (HHPA), using variable stoichiometric ratios is reported. The reaction was followed by differential scanning calorimetry (DSC). Two kinds of experiments were performed: (1) fresh samples were run at several heating rates, and (2) samples, precured a certain time in an oil bath at constant temperature (i.e., 80 to 120°C), were run at 10°C/min. Two peaks were observed in the case of the epoxy excess but only one for the stoichiometric formulation: the peak at low temperature was attributed to the epoxy copolymerization with the anhydride while the peak at high temperature was attributed to the epoxy homopolymerization. The catalytic effect of the OH groups present in the epoxy monomer on the copolymerization reaction was demonstrated by the decrease in the activation energy of the propagation step when increasing the epoxy excess. There is a catalytic effect of the copolymerization product on the homopolymerization reaction. Our simplest model, proposed previously for a catalyzed epoxy/anhydride system [J. Polym. Sci. Part B: Polym. Phys. Ed., 37, 2799], can be used to fit both isothermal and dynamical kinetic data.
