Abstract

13C NMR spectroscopy has been used successfully to study ethylene and propylene polymers. Some common polymer systems are summarized as follows:

C3 — → isotactic C3 — → irregular C3

C2 — → stereoregular C2C3 — → EPR — → ethylene-propylene oil

where polymer microstructure becomes increasingly complex as one moves from left to right. The 13C NMR spectral features correspondingly increase in complexity from left to right. C2 and C3 refer to ethylene and propylene respectively.
