NMR Spectroscopy of Polymers
Since 1H NMR spectroscopic determination of tacticity was established for PMMA
, many polymethacrylates have been converted to PMMA through hydrolysis and
subsequent methylation with diazomethane to be analyzed for tacticity [5].

Prediction of Polymer Properties
F. Effects of Tacticity The extent and type of stereoregularity of the polymer chains
can have a significant impact on many properties. Stereoregularity is usually
characterized in terms of the tacticity [143], which is depicted in Figure 6.24 for ...

PVC Degradation & Stabilization
Stereoisomerism essential for some polymers including PVC is better known as a
tacticity. Comparing optical isomerism with tacticity, one should mention that,
while physical properties of optical isomers are the same (except for light ...

A Laboratory Manual of Polymers
Tacticity was evident from the carbonyl carbon peaks near 180 ppm, the
methylene carbon peaks between 50 and 58 ppm, the quaternary carbon peaks
around 45 ppm, and the methylcarbon peaks between 10 and 25 ppm. The
methyl peaks ...

Tacticity in Vinyl Polymers The measurement of tacticity in vinyl polymers is an
area of characterization where NMR stands supreme. This is not to say that
infrared spectroscopy is not sensitive to the tacticity of a polymer. In
polypropylene, for ...
