“…These results are in accordance with the literature on macroporous 4-vinylpyridine-divinylbenzene [6,8,9]. Comparison of the pore volume of 4-vinylpyridine-divinylbenzene from this study with the pore volume of styrene-divinylbenzene [8,[10][11][12][13] from earlier studies showed that porosity controlling parameters, i.e., nature and amount of diluent and amount of cross-linking monomer changed the porosity of the two copolymers similarly and differently. The differences were the following: i) in general, the diluents create more pore volume in 4-vinylpyridine-divinylbenzene than in styrene-divinylbenzene, as illustrated in Fig.…”

4-Vinylpyridine-divinylbenzene copolymer beads of ~0.3 mm in diameter were synthesized by suspension polymerization technique. The beads were made porous by dilution of the monomers with phthalate esters. The porosity was varied by changing the diluent, by varying the degree of dilution, and by varying the ratio of divinylbenzene in the monomers. Pore volume, surface area, and pore size distribution were determined by mercury penetration method, and densities of the dried copolymers were determined by a measuring cylinder and a balance. Statistical analysis of the data shows that the surface area and swelling coefficient in acetone can be estimated from the pore volume value with a reasonable good accuracy. Pore size distribution curves for the copolymers having pore volume in the range of 0.1 ml/g to 0.8 ml/g are shown. One can approximately estimate the pore size distribution if the pore volume is known. The pore volume can be estimated with a reasonable good accuracy from the density of the copolymers.

“…[1][2][3] Porous structures are typically formed during the copolymerization of mixtures containing a divinyl monomer and inert porogens. [1][2][3][4] Polymer beads are usually produced by suspension polymerization in which stirring provides some control of the average size of the droplets and the resulting beads.…”

Macroporous, monosized poly(meta-divinylbenzene) and poly(para-divinylbenzene) beads have been prepared by the two-step activated swelling method with toluene or 2-ethylhexanoic acid as pore-forming agents. The type of divinylbenzene isomer as well as the type of porogen has a large effect on both physical and chemical properties of the monodisperse beads. Large pores are obtained with 2-ethylhexanoic acid as porogen while beads prepared in the presence of toluene consist of only small pores and exhibit a shrinking behavior upon drying. The beads have considerable amounts of residual vinyl groups at the end of polymerization, as determined by bromination and Fourier transform IR analysis. The morphology and texture of the particles have been investigated by scanning electron microscopy and atomic force microscopy.

“…The macroporous texture for these resins is obtained by using solvents in the presence of non-solvents or polymers as a porogenic diluent. Because the reactivity of divinylbenzenes in free radical polymerisation is significantly higher than that of styrene, a rather heterogeneous structure is obtained [6]. The preparation of copolymers of trimethylolpropane trimethacrylate (TRIM) and methyl methacrylate (MMA) (see Fig.…”

“…In such a case the microenvironment of the immobilised cationic polymer is approximately identical to that in the homogeneous situation, leading more or less to retention of the activity. Styrene-divinylbenzene is the most extensively studied macroporous polymer support [5,6]. The macroporous texture for these resins is obtained by using solvents in the presence of non-solvents or polymers as a porogenic diluent.…”

Reactive Polymers, 19 (1993) (Received November 13, 1992; accepted January 5, 1993) AbstractImmobilisation of expensive homogeneous catalysts is important for their application in commercial processes. Quaternised poly(4-vinylpyridine), which is a good promotor of the cobalt(II)phthalocyanine-tetra(sodium sulphonate) catalysed oxidative coupling of 2-mercaptoethanol, has been anchored on a macroporous resin being prepared by copolymerisation of trimethylolpropane trimethacrylate and methyl methacrylate. The performance of the catalyst was only slightly lower than that of the homogeneous analogue. This remarkable result has been attributed to the large pores, which allow a post-copolymerisation of 4-vinylpyridine with the residual double bonds leading to a flexible and accessible polymeric cocatalyst.
