摘要：

Electron diffraction intensities of two zones, (0kl) and (hhl), obtained from poly(ϵ-caprolactone) epitaxially crystallized on benzoic acid, were used for a quantitative crystal structure determination. Combining the data from epitaxially oriented samples with those obtained from solution-grown crystals permitted a nearly complete three-dimensional structure analysis to be carried out. The structural analysis demonstrates that the chains pack in the nonplanar structure in space group P212121 proposed by Chatani et al. rather than an alternative planar chain conformation. The R-factor is 0.199. © 1990, American Chemical Society. All rights reserved.
