This lecture explores the crystalline state of polymers, focusing on the regular and compact conformations they adopt upon crystallization. The slides cover topics such as which polymers crystallize, the mechanical properties of semicrystalline polymers, polymers that do not crystallize, the semi-crystalline nature of polymers, and the concept of 100% crystalline entities. Additionally, the lecture delves into the Bragg's law, crystal systems, PE crystal structure, space group operations, and the PE unit cell structure. It also discusses the regular chain conformations of isotactic and syndiotactic polymers, emphasizing the importance of compact chain conformations for close packing and enhanced cohesive energy.
