“…Similarly, a comparison of the 13 C NMR spectra of the monomer along with that of the homopolymer (Figure 2) also shows that upon polymerization, the peaks at 136.57 (CH 2  C ) and 124.98 ( C H 2 C) have disappeared. The 1 H NMR spectra of the other two homopolymers, that is, PS and PMMA are shown in Figure 3 and 4, respectively, and the peaks matched very well with that reported in the literature 23–29. There are two distinct peaks in the aromatic region of PS, which are attributed to the meta and para protons [δ = 7.1 and 6.5 ppm, Figure 3(e)], respectively, of the aromatic ring 23, 27, 29.…”

“…In the case of PMMA, there is a signal at 3.61 ppm [Fig. 4(e)] corresponding to the methoxy protons of the MMA unit 24–29. For the copolymerization, varying amounts of the different monomers were used to change the comonomer ratios in a systematic manner.…”

A new family of cycloaliphatic fused‐ring acrylic polymers based on 8‐hydroxymethyltricyclo[5.2.1.02,6]decane (TCD) has been synthesized by free‐radical polymerization. TCD‐methacrylate (TCD‐MA) was synthesized by reacting TCD with methacrylic acid in toluene via transesterification with p‐toluenesulfonic acid as a catalyst. TCDMA was polymerized in toluene with benzoyl peroxide as a free‐radical initiator at 80 °C. Copolymers were synthesized by polymerizing TCDMA with styrene and methyl methacrylate. The composition of the comonomers was varied from 0 to 100%. Homo‐ and copolymers were characterized by Fourier transform infrared (FTIR) and 13C NMR spectroscopy. Molecular weight determination by gel permeation chromatography showed that the polymers were obtained in very high molecular weights in the range of Mn > 50,000 and Mw > 80,000 with relatively low polydispersity. The composition analysis of both the copolymer series were determined by 1H NMR. The thermal properties of the homo‐ and copolymers were studied with differential scanning calorimetry and all the polymers were found to be amorphous. © 2004 Wiley Periodicals, Inc.

Phenoxyethyl methacrylate (POEMA) and butyl methacrylate (BMA) were copolymerized by free-radical copolymerization using a,a 0 -azobisisobutyronitrile (AIBN) in 2-butanone solution at 333 AE 1 K. Copolymers were characterized by FTIR, 1 H-NMR and 13 C-NMR spectroscopic methods and by comparison of the spectra with the corresponding homopolymers. Thermogravimetric analysis of the copolymers was carried out in order to know their thermal stability. Copolymer composition was established by 1 H-NMR analysis. Monomer reactivity ratios (MRR) were computed using the classical Fineman -Ross (FR) and Kelen -Tüdos (KT) procedures. MRR were also estimated using a nonlinear computational fitting procedure, known as reactivity ratios error in variable model (RREVM). The mean sequence lengths of the copolymers were estimated and suggest that random copolymers were obtained.

Affinity polymeric adsorbents useful for the separation of compounds which are derivatives of phenols, heterocycles and other compounds containing two polar moieties were prepared by a covalent imprinting approach. Such separation, for example, would facilitate the analytical detection and quantification of each individual compound especially when present in complex sample matrix. The synthetic method, utilised for the preparation of the polymers, is based on co-polymerization of diacrylate esters of hydroxyphenols (catechol, resorcinol and hydroquinone) with an appropriate cross-linker followed by alkaline hydrolysis of the esters and release of the corresponding phenol. The resulting swellable materials contain cavities with adjustable size and orientation of two carboxylic groups suited for the binding of molecules with appropriate size and complementary orientation of polar groups. In contrast to conventional MIPs the synthesized polymers have selectivity not only for the phenolic templates, but also for a group of compounds with suitable orientations of polar functionalities, such as aromatic nitrogen, amino or hydroxyl groups. Polymers demonstrated different affinity to ortho-, meta-and para-isomers of hydroxyphenols, hydroxypyridines and diazine heterocycles.
