摘要：

Tacticity and crystallographic considerations are used to predict fold models for a perfect crystal of isotactic polypropylene ( alpha -form). If we assume adjacent re-entry chain folding we conclude that the folding plane must be parallel to the (010) plane. This is in agreement with morphological experimental evidence. We also show that this result is likely to apply even to non-perfect crystals.
