“…The broad band at 3448 cm −1 was assigned to the stretching vibration of the silnanol groups [23]. Compared with the spectrum of MCF-copolymer ( Figure 3b), the FT-IR curve of Figure 3c displays a band at 1175 cm -1 , which was ascribed to the asymmetric stretching vibration of the O=S=O [24].…”

“…Thus, the length of the topological loops defined by super-crosslinks defines the pore sizes and heterogeneity in the bulk material while the rigidity prevents the polymeric network collapse. Obviously, this is related with the utilization of highly cross-linked P(S-DVB) resins as catalyst, [13][14][15][16][17][18][19] since the rigid pores defined by super-crosslinks ensure high surface areas. Accordingly, the existence of super-crosslinks affects the distribution of the sulfonic groups (see below) and facilitates the swelling and the accessibility to the active sites.…”

The microscopic structure of highly crosslinked sulfonated poly(styrene-codivinylbenze) resins have been modeled by generating atomistic microstructures using stochastic-like algorithms that are , subsequently, relaxed using molecular dynamics.Two different generation algorithms have been tested. Relaxation of the microstructures generated by the first algorithm, which is based on a homogeneous construction of the resin, leads to a significant overestimation of the experimental density as well as to an unsatisfactory description of the porosity. In contrast, the generation approach that combines algorithms for the heterogeneous growing and branching of the chains enables the formation of crosslinks with different topologies. In particular, the intrinsic heterogeneity observed in these resins is well reproduced when topological loops, which are defined by two or more crosslinks closing a cycle, are present in their microscopic description. Thus, the apparent density, porosity and pore volume estimated using microstructures with these topological loops, called super-crosslinks, are in very good agreement with experimental measures. Although the backbone dihedral angle distribution of the generated and relaxed models is not influenced by the topology, the number and type of crosslinks affect the medium-and long-range atomic disposition of the backbone atoms and the distribution of the sulfonic groups. Analysis of the distribution of the local density indicates that super-crosslinks are responsible of the heterogeneous homogenization observed during the MD relaxation. Finally, - stacking interactions between aromatic phenyl groups have been analyzed, those in which the two rings adopt a T-shaped disposition being considerably more abundant than those with the rings co-facially oriented, independently of the resin topology.3

“…Besides, sulfonic acid functionalized catalysts were illustrated to exhibit highly efficient catalytic performance for selective conversion of fructose into EMF. Kraus and Guney [22] found SO 3 H-functionalized ionic liquids used together with hexane resulting in a 54% isolated yield from fructose [28,29]. As illustrated in Figure 1, all the prepared solid catalysts consist of SO 3 H functionalized ionic liquids and corresponding polymers.…”

A series of SO3H-functionalized polymers were prepared and employed as heterogeneous catalysts for one-pot transformation of fructose into 5-ethoxymethylfurfural (EMF) that is considered to be one of potential liquid biofuels. A high EMF yield of 72.8% could be obtained at 110°C for 10 h, and the polymeric acid catalysts could be recycled for five times without significant loss of catalytic performance.
