In this thesis, combined quantum chemical calculation and solid-state NMR techniques were used to study the microstructure and hydrogen bond interaction in a series of crystalline and amorphous polymers, as well as segmental dynamics in polymer blends. This thesis basically consists of the following four parts:
1. Studies on the chemical shifts of two types of crystalline polymers, isotactic and syndiotactic polypropylene (iPP/sPP). By analyzing the influence of different initial configurations, conform...
