摘要

Double precision Fourier transform 13C nuclear magnetic resonance (NMR) spectroscopy was used to determine the microstructure of Acryloid K125-EA and high molecular weight poly(isobutyl methacrylate), PIBM. The PIBM was found to exhibit Bernoullian behavior and to have a predominately syndiotactic structure with only isolated meso additions. The triad distribution showed that only 5% of the monomer units occur in runs of three like configurations or longer. The Acryloid K125-EA was found to consist of 82 mole % methyl methacrylate, 12 mole % ethyl acrylate and 6 mole % butyl acrylate. Like the PIBM, this polymer was also found to have a predominately syndiotactic structure with more racemic additions than meso additions. (Author)
