The results of a Fourier transform spectroscopy study of the ionic polymers formed by methyl methacrylate and nickel acrylate and nickel methacrylate are discussed. The spectral features observed in the 4000??, 2250??, and 1030?? have been interpreted in terms of transmittance. Qualitative as well as quantitative information about infrared absorbent methyl methacrylate resin has studied. The Fourier transform infrared spectroscopy results indicate the amounts of nickel acrylate and nickel methacrylate are sensitive to the infrared absorption of methyl methacrylate resin.

Ortho-othro' metylene ether-linked high-ortho phenolic resins were studied with formaldehyde/phenol mole ratios, the amount of catalysts and several divalent metal salts in presence of toluene using the water separator. The toluene and water were removed as an azeotropic vapor mixture. This high-ortho phenolic resins were compared with conventional phenolic resins by FT-IR, and the average molecular weight and molecular weight distribution were studied by gel permeation chromatography. High-ortho phenolic ortho-ortho' linked percentage were about 81 - 90%, and this phenolic molecular weight distribution were more decrease than conventional phenolic resins.
