The Solid-State NMR of Polymers

Synthesis and crystallinity of poly(butylene 2,5-furandicarboxylate)

“…2b) [38]. The signal at 122.2 and 112.7 ppm were attributed to the furan ring in the crystalline and amorphous regions, respectively, since the pulse sequence without cross-polarization greatly enhances the 13 C signals from the amorphous region [39]. The result pointed out that the majority of furan rings were associated with the crystalline region, and its chemical shift was quite sensitive to the local phase change.…”

Characterization of styrene/methacrylic acid copolymers by 2D‐NMR spectroscopy

“…1 Ito et al studied the coisotacticity of methyl methacrylate-styrene, methyl methacrylate-co-␣-methyl styrene, 2 and vinylidene chloride-vinyl acetate copolymers by 1 H-NMR spectroscopy. Makushka et al 3 subsequently investigated the copolymerization of a methacrylic acid copolymer and gave valuable information regarding the sequencing and tacticity of monomer units in the polymer chain.…”

“…Bovey and Mirau used a statistical method to assign the sequence distribution of methyl methacrylate-styrene and methyl methacrylateco-␣-methyl styrene copolymers by 1 H-NMR data. 1 Ito et al studied the coisotacticity of methyl methacrylate-styrene, methyl methacrylate-co-␣-methyl styrene, 2 and vinylidene chloride-vinyl acetate copolymers by 1 H-NMR spectroscopy.…”

Stereochemical elucidation of complex α‐methyl and β‐methylene carbon resonances in poly(2‐hydroxy ethyl methacrylate‐co‐methacrylonitrile) by 2D NMR

“…3,4 NMR spectroscopy plays a significant role in the structure elucidation of polymers. 5,6 1D NMR in conjugation with 2D technique furnishes a very efficient method for studying the microstructure of polymers. 2D NMR spectroscopy has become a very important and valuable technique for determining the polymeric structure.…”
