“…As a rule, the higher the percentage of crosslinker in the polymerization mixture, the higher the surface area and the smaller the pores. The most often used crosslinker for methacrylate-based beads is EDMA [17, 18, 28 -30], although some other polyvinyl compounds such as trimethylolpropane trimethacrylate [31], 2-hydroxypropyl-1,3-dimethacrylate [32], and 2,3-dihydroxybutyl-1,4-dimethacrylate were also successfully used [33]. Figure 1 shows the significant effect of EDMA on the specific surface area of poly(GMA-co-EDMA) beads.…”

This review summarizes the preparation and application of chromatographic separation media based on methacrylate monomers with a major focus on highly crosslinked macroporous beads prepared from 2-hydroxyethyl methacrylate and glycidyl methacrylate, respectively. The effects of process variables such as composition of the polymerization mixture that includes monomers, porogenic solvents, and free radical initiator, suspension stabilizer, reaction temperature, and stirring are detailed for both classical and templated suspension polymerization. In addition, specific features of the preparation of monodisperse beads are also discussed. The performance of methacrylate-based separation media is demonstrated on numerous separations in a variety of chromatographic modes.

“…The specific aims of this paper are 1) a verification of our multimethodological approach to provide convergent and quantitative information on the nanostructure of swollen gel-type resins, 2) the critical and comparative inclusion of another powerful analytical tool, that is, CP-MAS 13 C NMR and 3) the evaluation of the effect of a trifunctional cross-linker on the overall morphology of the resins in their swollen state. It should be pointed out that TMPTMA has been already employed as cross-linker to produce macroreticular resins based on glycidyl methacrylate, [25][26][27] one of which resin was characterised with ISEC. [25] Results and Discussion Figure 3 illustrates the structure and Table 1 gives the molar composition and labelling nomenclature (MASF and AAD) of the investigated resins.…”

Six gel-type functional resins, that is, three poly-DMAA-co-TMPTP (DMAA = N,N-dimethylacrylamide, TMPTP = trimethylolpropyltrimethacrylate) samples with different degrees of cross-linking (0.6, 1.2, 1.7 % mol) and three poly-DMAA-co-MA-co-TMPTP (MA = methacrylic acid, ca. 5.5 % mol) samples with 1.7, 3.5, and 7 % mol cross-linking were investigated with ISEC (inverse steric exclusion chromatography), and ESR and CP-MAS (cross polarization magic angle spinning) 13C NMR spectroscopy after swelling in water and other solvents. This unprecedented combination of conceptually independent physicochemical techniques provides a thorough overall consistent picture of the morphology of the resins on the nanometer scale and of the molecular accessibility of the swollen polymer framework to the paramagnetic probe TEMPONE (2,2,6,6-tetramethyl-4-oxo-1-oxypiperidine) and to selected solvents.

Porous copolymer beads of 2,3-epoxypropyl methacrylate (glycidyl methacrylate, GMA) crosslinked with 2-ethyl-2-(hydroxymethyl)-propan-1,3-diol trimethacrylate (trimethylolpropane trimethacrylate, TRIM) were prepared with toluene and octan-2-one as porogens by suspension polymerization. With an increase in the ratio of porogen to monomer, the total pore volume of poly(GMA-co-TRIM) increases significantly, whereas the surface area hardly changes. The total pore volume also depends on the nature of the porogen, exhibiting a maximum at the larger GMA contents in the monomer mixture of 50% v/v with octan-2-one and of 60% v/v with toluene, compared to that at the GMA content of 25% v/v with a 9/1 v/v mixture of cyclohexanol and dodecan-1-ol [Verweij, P. D.; Sherrington, D. C. J Mater Chem 1991, 1 (3), 371]. The surface area decreases significantly with an increase in the ratio of GMA to TRIM, almost regardless of the nature of the porogen. The porous properties of poly(GMA-co-TRIM) was well explained on the basis of phase separation, particularly taking into account not only the solubility parameters of the resulting polymer network and porogen but also the rigidity of TRIM. The porous poly(GMA-co-TRIM) may be a promising polymer matrix of novel materials for separation of boron isotopes.
