Lecture
This lecture covers the solid state properties of polymers, including the crystalline and amorphous states, polymer mixtures, and mechanical properties. Topics include the microstructure of semi-crystalline polymers, factors influencing crystallization, degradation behavior of various polyesters, and the importance of polymer tacticity. The instructor discusses the implications of stereoisomerism, the transition between glassy and rubbery states, and the mechanical behavior of polymers under stress. Additionally, the lecture explores the phase behavior of polymer blends and copolymers, as well as the mechanical properties of polymers in terms of stress-strain curves and toughness.
