Crystallinity in atactic polyvinyl chloride
TL;DR: In this paper, a study of chain configurations and conformations leads to the conclusion that three different regular straight chain structures exist: the syndiotactic zig-zag chain, the isotactic helix and an isotactic straight chain.

Infrared spectra of high polymers
TL;DR: In this article, the spectral properties of polyethylene terephthalate and three deuterated analogs have been obtained in the region of 70 to 3600 cm-i, polarized spectra having been obtained down to 330 cm-l. This assignment suggests a modification of the proposed chain structure of this polymer.
