Summary
There are indications that the degree of crystallization in highpolymeric substances is of importance for the study of the mechanical properties. With regard to the crystallization of rubber up to now only few measurements have been made, mainly bij Field. The results, however, are in contradiction with some estimates of earlier date and therefore the necessity was felt to have them checked. An X-ray method, in some respects differing from Field's, was developed, the results of which diverged considerably from the figures reported by Field. The present article deals with the description of the method.
