β¦ Synopsis
With the increased interest in stereospecific polymers, it becomes important to know the degree of isotacticity and the distribution in the lengths of stereo blocks making up the polymer molecules. Coleman' has suggested a method of measuring the degree of isotacticity based on melting points.
Another method of estimating isotacticity would appear to be possible from measurements of the maximum attainable crystallinity of a given polymer. The greater the isotacticity (or syndiotac-

Important chemical and mechanical properties in semicrystalline polymers are determined by the noncrystalline or nonordered regions. Hence, characterizing these regions is important in developing a morphological model to better define and predict the chemical and mechanical behavior of polymeric mat
