1. Combining information from Ref. 11 and from
2. Several factors tend to keep these growth fronts separated; there is a tendency for lamellae to splay apart (see Ref. 10); also, leading edges of layers spreading from a screw dislocation are terraced and thus displaced laterally from one another.
3. It is convenient to reserve the term intercrystalline link for those fibrous crystalline links that can be seen directly under the electron microscope; monomolecular links, or undetected links involving at most a few molecules, we shall term tie molecules.
4. Orienting influence of the substrate is well preserved in such compact structures grown from concentrated solution only if polymer of relatively low molecular weight is used.
5. There may be some significance to the fact that uniaxial extension of a coiled molecule, such as might follow double nucleation as considered earlier, tends to convert it into an irregularly folded bundle of parallel molecular segments, but further concern with such detail is not at present profitable.
6. Markedly open texture of spherulites as in Fig. 1 is partly an artifact arising in fast crystallization in a thin film.
7. There must be considerable interpenetration of this kind, since an observed tendency for continuity of extinction rings across interspherulitic boundaries implies strong coupling of lamellar orientation.
