Course Objectives :
1. teach students how to completely characterize the melt state of polymers
2. teach students various basic rheological techniques
3. teach students how to characterize some major processing operations
4. teach students how to approach typical industrial processing problems
5. teach students how to extrapolate basic rheological data to processing operations
6. teach students how to draw graphs and analyze real data which doesn't fit any format
7. to expose students to fundamental theories of polymer melt flow to give them a sophisticated look at what the data is saying.
Course Outcomes :
1. Given an unknown polymer, completely characterize the melt state and suggest processing parameters
2. Given an extrudate which is less than satisfactory, suggest changes in the operation which may resolve the problem
3. given various problems in injection molding, explore various ways of how to solve the problems.
4. given basic rheological data, how to analyze and interpret it.
5. mathematically model the rheological behavior of a complex melt.
