CHE 543 Polymer Science and Technology
3 Credit Hours
This course is intended to provide a broad overview of polymer science and engineering. The emphasis will be on the synthesis and structure of polymeric materials, the crystalline and glassy states, solution and melt properties, phase behavior, mechanical and rheological properties.
A BS Degree in engineering or related field. Students uncertain if they meet the prerequisites should contact the instructor.
By the end of the course the students will be able to:
- Understand and describe the manufacture (using both traditional and non-traditional synthesis schemes) of commercially important polymers using concepts from chemical kinetics and equilibrium thermodynamics;
- Present a basic understanding of the structure of polymer chains in solution (including molecular weight, molecular weight distribution, chain conformation) and methods to characterize polymers in solution;
- Describe polymer phase behavior using basic Flory-Huggins theory of polymer solutions/melts;
- Understand the structure of polymers in the solid state and describe the effects of structural organization (i.e. crystallinity, liquid crystallinity, phase separation) on molecular and end use properties of polymers, and recognize the basic stress/strain and viscoelastic behavior of polymers based on a knowledge of structure and thermal properties (e.g., melting and glass transition) and apply the Boltzmann superposition principle and Williams-Landel-Ferry equation to predict viscoelastic behavior of polymeric melts.
- The nature of polymer materials and polymer microstructure: including branching, networks, tacticity and copolymers;
- Polymer synthesis: step-growth and chain polymerizations;
- Kinetics of polymerization: the kinetics of step-growth and free radical chain polymerizations; relationship to molecular weight;
- Statistics of step-growth polymerization: the use of statistics in describing molecular weight distributions in step-growth polymerization;
- Copolymerization: the kinetics of free radical copolymerization;
- Structure: chain conformations, amorphous polymers, and the morphology of semi- crystalline polymers;
- Crystallization, melting and the glass transition: an introduction to crystallization kinetics, melting and glass formation;
- Polymer solutions: the Flory-Huggins theory and phase behavior;
- Measurement of molecular weight: osmometry, light scattering, viscosity and size exclusion chromatography; mechanical and rheological properties: stress/strain behavior, visoelasticity, non- linear mechanical and rheological behavior, ultimate properties.
