Observation of polymer using differential interference method Description: An example of observing the formation process of interpenetrated spherulite under temperature control of the specimen. Spherulites A1 and A2 (PBSU), and another spherulite (PVDCVC) nucleate almost simultaneously and the internal contrast of PBSU is higher than that of PVDCVC sphetulite. The photo (b) shows that A1 with higher growth rate is in contact with B1 with lower growth rate and the region that shows higher contrast ratio extended afterwards in the direction opposite to the contact area within B1. [Photos (c) and (d)] Even after the fibril(lamella) of A1 had penerated through B1, A1 kept growing in the melt as can be seen by an arrow in the photo (e). When A1 and A2 came in contact with each other, the growth stopped and the spherulite boundary was formed. Sphrulites of PCDCVC also formed boundary with each other in the same manner. However, spherulite boundary was not observed even when PBSU and PVDCVC came in contact with each other. [Photos (d) to (f)] The contrast within the spherulite of PVDCVC changes before and after the penetration of PBSU. This fact allows the analysis of interpenetration process.
