Abstract：An overview of the use of solid state NMR for characterization of physical phases and molecular mobility in multi-phase polymers is the topic of the lecture. Application areas of the method and its importance in industrial research will be briefly discussed. Then, the morphology of semicrystalline polymers with different crystallinities will be overviewed. In the follow-up, it will be shown that different contrast to crystalline and amorphous domains, which is intrinsic for traditional methods for crystallinity determination, can cause discrepancies in obtained values, and a combination of methods helps to gain a better understanding of semicrystalline morphologies.

Bio：Victor M. Litvinov, Ph.D., is a guest professor at Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. In 1973, he obtained master’s degree in chemical technology from the Lomonosov Moscow State Academy of Fine Chemical Technology. From 1973 to 1985, he worked at the Scientific Council of High-Performance Polymer Materials at the Presidium Academy of Sciences of the USSR. He received his Ph.D. from the Nesmeyanov Institute of Organoelement Compounds of RAS in 1978. Between 1988 and 1989, and from 1989 to 1991, he was awarded fellowships by the Alexander von Humboldt Foundation and the German Research Foundation. From 1992 utill 2015, he was employed at DSM Research in the Netherlands. Subsequently, he established a consultancy company and continues to conduct research in cooperation with universities and companies, providing training and assisting in the development of time-domain NMR expertise.
